Monitor Audio Pl 300ii vs. KEF Reference 5


I own the KEF Reference 5s.  I borrowed the Monitor Audio Pl300 ii speakers for comparison, which is still under way.  Thoughts so far:  Both are good speakers.  The KEFs provide a lot of detail.  Listening to classical music, you can hear orchestral instruments and sections pretty clearly.  Background and counter melodies can be identified. Piano music is very realistic.  The MAs do not provide as much instrumental detail but they do have a more mellow, deeper, broader sound.  Which is better is really a matter of personal choice.  As I said, I’m still listening so these are some quick preliminary reactions.  More later.

The Monitor Audio PL-300 II can reveal all the 8 different properties of sound. The Kef cannot reveal a 3D stage on facts. Based on the fact that it is not able to create and reveal this property of sound.

The other thing is that the PL-300 II can create a stunning level in diversity in height of voices and instruments. The Kef is what I call a hifi loudspeaker. Based on the fact that by sound easily can be proven that it misses these properties of sound by facts.

Even the other properties of sound can be filled in a lot better by the PL-300 II.
The AMT tweeter is a lot different than a dome tweeter. And it needs to be used different to get the full potential. We can proof and have proven that we do not have this issue that it is too dark. 

We have proven that is it more open and creates even more details than speakers with a dome tweeter. The problem is that people do not understand sound and music either.

They all do audio by trial and error. Selecting audio this will never make yolu understand what you are doing. You need to understand the properties of sound first before you can understand audio.

We will place many reviews of clients who went from a trial and error system to a Tru-Fi system. We will translate all the reviews in english as well. 

In a Tru-Fi system the Platinum II series is a titally different loudspeaker than peolle know it for the trial and error world. Our clients will tell this in their reviews. 

When I see the systems used for Platinum II reviews I can see the mistakes they made. Regarding the high frequencies they all make simmilar mistakes.
People are always talking about brands and products. In the Tru-Fi world we only focus on the properties of each individual part in an audiosystem. This is a totally different way to create an audiosystem. The differences between our way and the trial and error world could not be bigger.

The results proof how superior each Tru-Fi system is. We do a lot of research all the time. And no we will never give details for free. We are now talking with different manufacturers. It is my knowledge and insight. I do not share this.

We do a lot of modifications and use many tools to limit smog, magnetism and high frequent noise. I will never share any of this information. Based on the fact that I made the leap bwteeen us and the rest a lot bigger. And I want to make this leap bigger each 2 months of mine.

When we install an audiosystem we use for far over 7000 dollar in high tech measurement tools. Most audio shops only take a few simpole and cheap tools with them. In vision we also use high tech calibration software and tools of over 7000 dollar.

The Tru-Fi world is a world what is 20 yeras ahead of the trial and error world. By doing research all the time we can make this leap bigger and bigger.

We will proof that trial and error is an important reason on facts that it is so ineffective. That is why we will share the stories of people who went from a trial and erro system to a Tru-Fi system.


Sound tells the truth, and does not lie. It is very easy for us to proof that trial and error systems miss essential parts of sound. When new clients take their own music with them we see that it is very easy for them to understand which parts they do not have in their system at home.

That is why we will place all their stories. We will even start a videochannel. We own Sony professional video 4k equipment and will use this soon for our website.
People often blame the loudspeakers. But.....in reality the mistakes are often due to other parts. Based on the fact that most people have not a lot of insight and knowledge regarding sound, the acoustics, smog, magnetism, high frequent noise they asume that the problems are caused by the loudsoeakers. This proofs how complex sound is and that peolle need to look further before they can understand the real reasons which causes the limitations.

I did send a new client to hear the PL-200 II at an audioshop who work by trial and error. I wanted to make him understand that a PL-200 II is a totally different loudspeaker in their world compared to the Tru-Fi world.

He said the same about the low frequencies as mentioned above. But....you need to understand the loudspeakers first before you can understand which kind of amp, source and cables you should use.

The Platinum serie has by far the best response of the mid en low freq drivers in their price range and even far above. Based on the fact that their material (ceramics with aluminium and carbon fiber) are lighter and they do no use a voice coil like all the other brands. This gives them a lot less compression and a lot more energy even at low volume.

But....due to the acoustics most create limitations regarding the energy of the Platinum loudspeakers. The other limitation is that most amps are not great in delivering enough current.

Becaus in the Tru-Fi world we can proof that we have a superior controlled low freq. range and this with much more layers than with any other brand in this price range and far above it. The other benefit is that the energy is fully free for the loudspeaker. You can feel the energy of the instruments in front of you far away of where the speakers are positioned.

The other thing what is done wrong by many shops and also during reviews is the fact that they do not understand how AMT tweeters works. And how they need ot be used the right way. We have proven that we can create much more details with them compared to other loudspeakers in the same price range.

We will place different reviews of clients soon who will confirm this by comparing their loudspeaker they used before the Platinum loudspeakers. Sound always will tell the truth. Each single person can hear it himself and compare it with his own loudspeakers.

We do audio by shootout so people can compare their trial and error system vs a Tru-Fi system. People will always want theat system that impresses them the most. And what creates the most emotional experience during listening to their own music.
We will place many reviews soon and we will make professional videos as well. We are working on this right already. I have put the list and explanation of Tru-Fi many times. Just read back in other threads.

Tru-Fi has nothing to do with brands or products. It is universal and can be used for each single brand and product. It will give you the full DNA of each single part in your system.

People always asks which brands and products I use. My clients always start to laugh when I show them the reactions of trial and error people. Because they understand that the way we work is so much different.

Most things we will never share or make photos of. We go into details so much further people cannot even imagine. I have extracted both sound and vision in very small parts. Which most people have no idea of. When I visit an audioshow it is always a contest of faults.

But they cannot hear and see the faults they make. Based on the fact that they are not able to think that far into details. For the first time we share this with manufacturers. But....I will never give this for free. They and all other people have to pay.

But it is so much more effective than all other trial and error choices that it will bring many brands and people to a much higher level in realism and emotion.
We create sound by displaying all the 8 different parts of sound at a high level. This means each single person can easily understand and hear each single property of sound during listening.

What we see and hear is that all individual persons find their own music played at a superior an more emotional level wat they have with their own system. They also say that they never auditioned an audioststem in any shop what comes close to this level.

I a a born perfectionist and started doing audio when I was 6 years old. This is not my job or hobby. It goes so much further than any person can ever understand. I want to outperfrom any other person in result. I al only interested in being the best. This I proof with sound. This is a part of who I am as a person, like a second nature. It does not cost a lot of energy at all. I can understand it within a split second.

I am working in audio for over 20 years of time. I never have met any person who spend that many hours on sound&vision as I did. The other important thing is that I have not met any person who also can think and work by properties of sound

Based on the fact that I am 100% convinced that this is the only way to understand and guide any audiosystem. For me it is very simple to explain and make people aware which parts are missing in their system. I never met any person who said; but my system can reveal all the propertirs of sound.

We can proof by sound and on facts what is missing. There is not even any discussion possible. Tru-Fi is over 300% more effective than any trial and error created system. We proof this difference by shootout and comparing. Audio is all about shootout and comparing.

The sound and stage what you can hear will always tells the truth. And this I love most about audio. We create a superior sound and stage than what people own. They all react the same way over and over again. This is want themselves. The have auditioned their own music by a Tru-Fi system.

It blows away all your thoughts about audio and music. People have no idea what it really means when I say; I work at 0.25 millimeter precision. Everything I write is exactely as I wrote it. A born perfectionist will never except any fault and lower level in result.

The precision of trial and erro is very limited and we can proof this again by sound. After this there is never any discussion posible. The sound and stage will make you aware within a few seconds that the world you hear your music is totally different.

Using all the different properties of sound is just a part of Tru-Fi. Using high tech measurement tools also brings the result to a superior level. This also counts for all the adjustments we do regarding smog, magnetism and high frequent noise.

The Platinum loudspeakers can proof by Tru-Fi that they can outperfrom all other loudspesakers. Based on the fact that in any shootout they are more complete and have less compression  in sound. Trial and error will always create a result which lacks differences parts of sound.

Tru-Fi proofs for all our clients that these systems create a much lower level in emotion and excitement. That is why it is very easy for them to slle their audioproducts.

The only parts in their system they can keep are thiose who can reveal all the different properties of sound. Each single part what is incomplete has to go. Based on the fact that each single part what is incomplete will limit the endresult. Again there is no discussion possible that it has to leave.

Tru-Fi makes you understand both sound&vision a lot easier. Because you only focus and work with all the different properties of sound&vision. Since 2,5 years we work with vision the same way. And again the results proof that we can easily outperfrom all our competitors.

Also for vision we use for over 7000 dollar in high tech tools and calibration tools and software. We even here we do many adjustments regarding smog, magnetism and high frequent noise. These parts also influences the vision negatively.

Doing audio by trial and error it is not possible to understand why the stage and sound is what you hear. I was in 1998 aware that I needed to learn why a loudspeaker is so different than another one. That is why I have done thousands of tests. We had 5 different listening rooms. And I could borrow almost everthing I wanted to test and hear. I did borrow expensive products a lot all the time.

We can and wil proof that Tru-Fi makes trial and error look silly. And that on facts. You can easily learn to people what all the different properties are of sound. I will use people from the conservatorium a lot during presentations. As I will use curtains during demos.

It is our goal to help en bring many people as possible to a much higher level in emotion and realism than their own system can create. Audiogon is a place where you can put advertisments. When we are ready we will use it, for now this is too early. I am not allowed to make any kind of advertisment for us. I respect that. I will place different reviews in english overhere from our clients soon. I hope they will not remove them.


At the end you can hear it yourself and you have the freedom to judge. Only by hearing you can give an opinion. People need to stop making audio that personal. Audio is all about sound.

I will place the reactions of people overhere. So you have an idea how they experience it. You even can make contact with them by Messenger of Facebook or email. We don't hide anything. We just do both sound&vision by what you can hear and see.

It is up to each single person how they experience it with their own music.
People cannot understand and use cables the way they can be used. That is why the people who are in charge of Audioquest Europe will visit me in September. The reason why I invite them is due to the fact that I will show them how limited the level is what they can use and reach of each cable by trial and error.

When you use Audioquest by Trial and Error it becomes a different cable. The same counts for Monitor Audio loudspeakers. And all other brands we use. Only Tru-Fi gives you access to all the different properties of sound they own.

And again we can demo this so they will understand what I mean. Sound makes it so much easier to understand my words. When you never auditioned a Tru-Fi system my words are just words. But when you hear it my words become the new truth.

And this has a huge impact on all people.
The only thing what is needed, is to hear it yourself. It is that simple. 
Most people have never really thought about what sound is and how it works. The facts proof that most even cannot answer the most simple questions. What do you think you are doing?

When you think and believe that trial and error will give you 'your' sound you are too stuppid to face the truth. When I talk these days with people about trial and error. They all agree that I am right that there is no foundation at all.

People don't like to be faced with the truth and facts. It proofs that the way to do audio is not the best way. People who will never accept that they made a mistake will stay where they are. But....when you want to leanr something and you want to create a much better quality and sound you have the freedom to use it.

I have to admitt that there is not enough good and honest information about audio. I have talked a lot with many distributers and even with manufacturers about the knowledge and insight in audio. And they all see and hear that the knowledge and insight is getting less each single year.

When you let people audition an audiuosystem what can reveal all the different properties of sound they all react the same way. Because they can hear their own music at a level they never heard before. It is the same music, but it has so much more to offer. And they can hear things that they never noticed before.

The acoustics influences the sound and stage the most. For that this is an essential part to learn what it does and how it works. This is why we spend the most time in research and testing in this part. With our measurement we have proven how much more details in the whole frequency rannge we can create compared to what we call 1980 audio.

Most people cannot even imagine how much they loose by the acoustics of their room. Beside the acoustics audio is being limited a lot by smog, magnetism and high frequent noise. Most people even don't know these parts.

We started to spend a lot of time on electricity for the beginning in 2015. We always have a lot of contact with different specialists in areas they have a lot of knowledge in. And we share a lot of information. And when I see what we accomplished in these parts it is stunning.

It proofs how these parts negatively influence the sound and stage. And money will not help you. Most people have no idea how limited the real quality is they actual can use of each part in their system. We use many different tool and have many different modifications regarding smog, magnetism and high frequent noise. 

It is so much more effective than spending more money on loudspeakers, amps, spources and cables. Each decision we make the results are the most important part. All decisions we make are founded on the best efficiency we can create and reach.

Tru-Fi has proven over and over again that it outperforms each audiosystem  what is being created by each person themselves by trial and error. Even this can easily be explained. Based on the fact that it can reveal so much more details and layers of each recording. And all different properties of sound are so much more easy to observe. 

Our S.A.P.-measuement gives us access to more details and layers in the whole frequency range. But the other important benefit is that we have so much more control and authority than people ever experienced in their life.

All the tools and modifications we do limited the effect of smog, magnetism and figh frequent noise a lot. This gives us access to a much higher level of each part in an audiosystem. When you are an extreme perfectionist as I am, everything you do is focused on result. There is never room for error. This is in my world only for the born losers of this world.

Audio done by trial and error is the level of a child. Based on the fact that there is no foundation. This again can be explained by facts. Most do not like to hear this.

But what would you like to hear? The truth or the thing you would like to hear. And believe me there are a lot of people who like to hear the things they prefer to hear. Even if that is not the truth. We cannot help these people. We work by facts and thye truth. Because in our world this is the only way to do it right.






When you work by Tru-Fi you use all the different properties of sound. So you judge each audiosystem by all these different properties. This has nothing to do with insult. We are only talking about facts. And when you cannot deal with the facts, it is your problem.

The people who own products which are incomplete in properties are the one who are screaming overhere at Audiogon. I am sorry that you own audioproducts which are not that good. What you hear is what you get. That makes audio so easy for everyone to understand.

Each single person will always choose and desire that sound and stage what influences their emotion the most. This has nothing to do with personal taste. This is due to how our human emotion works regarding music and sound. This works for each person the same way.

Maybe you have a different tatste of music, but at the end all music possesses properties of sound. And again we are talking about facts. And when an audiosystem lacks different properties of sound this system will have a lower level in emotion for each single person.

When you hear your beloved music with a system what ia able to reveal all the details and different properties this is the one you will always choose blind. Based on the fact that our emotion will have a preference for this kind of sound and stage.

Most people who have audio as a hobby have not the insight and knowledge about all the different properties of sound. As they do not have a lot of knowledge and experience with the acoustics, smog, high frequent noise and magnetism.

When you do audio bu Tru-Fi it proofs over and over agian how much more intense and emotional people experience their music. And again this can be explained by sound and telling people about all the different properties of sound.

When you choose all your different parts of your system by trial and erro you will never understand why the sound and stage of your system is what you hear. You are gambling and hoping that you took the right decision. 

But Tru-Fi can proof and make clear that these trial and error systems always miss essential parts of sound. When new clients hear with their own music a Tru-Fi system they noe in a few seconds that it is a totally different world.

You see their smile on their faces and often they say; I never experienced mu music this intense. Because they can hear their music for the first time with all the detail and layers it owns. And this makes a big impression on all people.

What all our clients have in common is that they all use their systems so much more often en they listen for a much longer time. This can easily be explained by the fact that all different properties of sound can influence our emotion.

When you become aware that your system can reveal all details and layers you want to experience this again and again. That is why many of our clients use the word; addictive. We spend a lot of time in reading about how our emotion works regarding music.

It gave us so much information to understand how sound and music works. We use a lot of this information for all our modifications and tools we use in our systems.

I learned during classical live concerts that both voices and instruments are very direct and small in dimension when you audition it in real. We call this intimate sound.

We use acoustic songs with only a few instruments to explain people what intiamte sound is and how it works.

When you compare a 2D system vs a 3D system, it ie very easy to understand that the 2D system the intimate sound is alsmot gone. This is due to the fact that there is no space around de singer. When you play the same song with a 3D system, it becomes clear how much more intense the voice becoms during listenig. It brings you closer to the music.

First of all you need both amp and sources who are capable of revealing all the properties of sound. I will not tell in details how this works.

But I can say this; the PL-200 II is in a Tru-Fi world a better loudspeaker than the PL-300 II due to how it is build en the size. I always say: you need to leatn to look further. Working by Trial and Error will never make you understand what you are doing. 

The facts proof over and over again that trial and error has no foundation on which you made your decisions. You are just guessing and that is why trial and error is so ineffective. 

The Monitor Audio Platinum loudspeaker is in a Tru-Fi world a totally different loudspeaker than in the trial and error world. Based on the fact that in a Tru-Fi system all the 8 properties of sound are used. In a trial and error system most of the time they miss 2 or often more properties of sound.

Most of mu clients said; we would never have bought a MA Platinum in any trial and error system. They auditioned it also at other shops and shows. Than it is an inferior endresult based on the properties which are missing. And the fact that other properties are filled in at a much lower level.

I will never give my huge advanytage and knowledge to others for free. I use it for myself and for the manufacturers who pay. This is what I do for a living. Tru-Fi makes any trial and error system sounds inferior. Each audiosystem hat can reveal all the different properties of sound and even at a higher level will influence your emotion so much more.

You always will choose for the system that can influence your emotion the most. This has nothing to do with personal taste, but due to the fact that our emotion almost works the same way.

The only that is a personal matter is the fact that people have their own preference in music. But....the emotion which the music possesses works always the same way. This can be proven over and over again by Tru-Fi.

Audio is done by shootout. And the most convincing and emotional sound each person will choose. That is why we create and use all the properties of sound. And second we use all the aspects which influence the human emotion by music to the max.

That is why Tru-Fi is so much more appealing than any trial and error system. When you listen to your system with your beloved music and you compare it with a Tru-Fi system what can reveal all the properties of sound with the same music we see that each single person directly understands that it is superior.

Often they say; I knew it only in a few seconds. This is how big the impression is between an incomplete audiosystem vs a system what can reveal all the properties of the same music. I spend so much time in the past regarding sound and the human emotion. That is learned to use them at the max and this maxes a huger difference in endresult.

I think the biggest problem is that sound and stage is very complex. You need to understand many many different aspects to be able to understanbd why the stage and sound is what you hear.

I did this for over 20 years of time. Thousands and thousands of hours. Over and over again. And it never stops. I learned to create both sound&vision. This is not even comparable with doing sound&vision by trial and error. The endresult is of a different level and from another planet.

The people who do not like what they read are the one who will react. They are only able to react by irritation and greed. They cannot react on the thread.

Tell us in details how you found and choose your system. Audio is all about sound and the quality in realism and emotion you can create. 
The Pl-300 II is a difficult loudspeaker in most normal houses due to trial and error systems. You all do audio at 1980 inside and knowledge. And this without roomcorrection.

In a Tru-Fi world we can even place PL-300 II in a small room. But we have Statement Audio Pro-measurement what creates a world most people don’t even know.

Each loudspeaker own properties and they have a certain level in how good they can fill in the properties they own. When you do audio by trial and error you cannot read a loudspeaker as we can read it.

With this I mean to understand the full DNA of the loudspeaker. Before you can make any decisions about which amps, sources and cables you will use, you need to understand the DNA of that loudspeaker.

For me it is always very funny to see which brands and products they choose. It proofs that they are making all their decisons by gambling and hoping for the best. Products and money will not help you to create the best balance and choose the right products for your loudspeakers.

Audio does not work like this. You all believe that you create the best endresult by trial and error. But the truth proofs that trial and error is extreme ineffective. And this will never change. You have no idea what the properties are of each individual part in your system. This proofs on facts that you cannot guide and controle your system.

In A Tru-Fi world the Platinum loudspeakers will always be superior to all the different Kef loudspeakers. Due to the fact that it can reveal more details and properties of each recording. And this will create a much more emotional feeling for each person.

But........in the trial and error world the Platinum is not that much better than the Kef and it can even be less. You all think that this is the truth in quality of any audio product.

But Tru-Fi creates a different world and a totally different outcome with the same loudspeaker. We will let our new clients tell their own stories. So you can read how they experience their incomplete loudspeaker in the past. And how Tru-Fi changed their perspective and ideas about audio. And what their Tru-Fi system changed in how often they use their system. And what it does with their emotion.

You all keep on focusing on brands and products. In the Tru-Fi world we are only interested in the properties/DNA of each single part of an audiosystem. Because this is the only access you will get to understand why the sound and stage of your system is what you can hear.

There is no other option to even have a chance to understand it. All the other options are all founded on trial and error. I talked with many people about trial and error. These people are all persons who work in audio for a long time. No one could explain to me that he uses any kind of foundation.

They all agreed that is is based on gambling and hoping for the best. So when people can tell us how they found their decisions, please write it down. And let us know.


Both the Blade and Reference have the same kind of distortion in the middle/high freq. range. When you use an amp who can build a huge deep and wide stage like a Pass Labs. You will hear how limited the stage depth and width is.

We can create a stunning level in diversity in height of voices and instruments. Even when you use the best audio products who are able to create this, the Blade and Ref will show you that the height of voices and insttruments are on the same height. We call this a hifi stereo parameter.

There are not many loudspeakers brand who can reveal diversity in height and also all the different properties of sound. Most people who do audio by trilal and error have no F. idea anything about sound. They have no idea what they do and how they make their decisions.

You only can understand audio when you understand all the different properties of sound as you know all the different aspects like smog, acoustics, high frequent noise and magnetism who negatively influence the sound and stage.

When you do not understand this, you will never understand audio untill you die. This is a 100% fact. Maybe it is not what you want to hear. But this is the truth. Trial and error has no foundation and no one can change that.

People need to learn to think further. When you are not able to think further you only can do audio by gambling. Audio is all about sound. And sound is founded on properties. These are all facts. And by sound they can easily be proven over and over again.

Most people don’t like to hear the truth. But when you cannot and will not face it you will have a limited level in sound and stage untill you quit. Trial and error will never make you understand both sound&vision. This is why you never can guide and understand it.

There is only one way to go and this is being able to think and work in properties. I am sorry for all people that this is the truth. When it would be different I would have written it.

Each brand and product owns properties of sound on facts. When you use brands and products who are not able to reveal all the different properties of sound you will use the PL-200 II or PL-300 II at a very low level. All your decisons are chosen by gambling. Based on the fact that when you would be able to think in properties you would have taken totally different decisions.

Take a look on google and search for pictures of the Blade. Take a good look at the way they made the cabinet and look for how they connected the drivers inside.

After this just use your brains..........


You are going to a shop and they will let you hear different loudspeakers by trial and error. Because this is how the worlk all their life. And they have no idea as you have no idea how to do it differently.

The truth is, this will never give you access to a high level in endresult of any of these loudspeakers. I can garantee this for 100% and I can even explain  it.

People all believe and think that you are only able to create and choose your system by yourself. Bases on assumptions this iw what we believe. Like you believed as a child that Santa Claus exist. Now you know the truth is different . Tru-Fi proofs that trail and error is one big F. laugh. It proofs it not on a personal opinion but on facts.

All people will choose that system even blind when it is able to reveal all the diferent properties of sound. Your emotion and my emotion work quite similar. 

I did send a new client to a audioshop to listen to the PL-200 II and some other loudspeakers. He found it a good loudspeaker but not that unique. This is what I knew how he would react.

I know exactly the DNA of the stuff he owns now and which were used during the demo. These products can only create about 4-5 different properties of sound on facts.

They other day I did send him to a client of us with the PL-200 II in a Tru-Fi system. He said alter that day on the phone: to be honest I knew it in a few seconds with the first song I listened.

We always advice new clients to take their own music with them. He said; this was the best system I ever auditioned in my life. It can be explained easily. He is a musician and could hear for the first time things he also can hear when he plays.

He was amazed by the diverisity in height of the instruments. This is what we can reveal with a PL-200 II. Most brands and products cannot create this property on facts. What is missing will never be there.

Music is emotion you only can expeience and feel this emotion when an auddiosystem can reveal all these different properties. But trial and error always creates incomplete systems. It will be an utopie to experience all the emotion.
Audio needs parameters. When they would give the world of audio the right and true parameters of sound it would become a lot more easy to understand how audio works. But first of all they have not the right insight and knowledge. And second they do not want people to understand it. 

This way they can let people believe what they want them to believe. I am addicted to music since I was a child. Music need to be played as realistic as possible.

Music owns different properties. This has nothing to do with a personal taste. When you cut of a property of sound of a recording you will experience the same music less intense. When you cut of another property it will become even less emotional than before the last situation.

For music you need audioproducts who can reveal all the details and layers of a recording. This has nothing to do with personal taste. These are 100% facts.

But the problem in audio is that most products cannot reveal all the different properties of sound. This will have a negative influence on the human emotion. I think and believe that the products which are produced are incomplete based on ignorance.

That is why we want to create new products so people come closer to the truth of their music. We want as many people possible to experience their beloved music with maximum emotion.
dear Audiodoctor,

You use 5 parts how to create an audiosystem. But...the facts still proof that they do not know and understand the properties of all the different parts of tnji system. Choices will be pure in random order.

They set up different loudspeakers. For example the Platinum 200 II. They still cannot read the DNA/properties of the loudspeaker. I know the DNA of many brand and loudspeakers.

Tru-Fi can proof easily that most created systems are incomplete on facts. This means it is very easy to let people hear the parts which are missing.

I also did a lot of research in cables in over 20 years of time. Even cabel brands have their own DNA/properties.

Buth when you ahve no idea what the properties are of this cable, you are still making any decision by trial and error. You will listen to the endresult and you still have no F.idea about the different properties of each part in that system.

Even without understanding the properties, sound is evne so much more complex. I spend the msot time in the last 8 years on the acoustics. Based on the fact that this part has the biggest influence on the sound and stage of any audiossytem.

But in 2015 I started to do again research in electricity. I did spoke many different specialists during these tests and research period. I fouces on 3 parts also; smog, magnetism and high frequent noise. Now in 2018 I can limit these negative aspects on sound and stage a lot. 

People have no F.idea how extreme negative these parts can influence both sound and stage. Like is also influeces vision negatively which we also tested.

I will never give the names, but most cable brands are not able to reveal all the different properties of sound. But people have no idea what the properties are of the cabels they buy. Due to the fact that trial and error will never give them this information.

I had contact with Desmo]nd Harrington in the past for many years. I was surprised that even they work by trila and erro. And they have no idea about the dna/properties of other brands and loudspeakers.

Again they also can use ans get access to s limited level of their own made stuff. Due to the fact that I could see that they use brands and products which are incomplete on properties.

But they also cannot think in properties. I owned many Pass labs momnos and amps in the last 9 years. I owned the XP-20 for some time. But I was able to create a superior level with the modified Onkyo PR-SC5509 with our own measurement.

It was able to reveal more layers and details in the whole freq. range. And Desmodn wanted to buy a 5509 himself. But I had to laugh and wrote; this doesn't make sense at all. You do not own my brians so you cannot use my insight. Only when you can think and work by properties and you onw a photographic mmemory as I do you could understand it.

It took me many years and thousands of tests and hours to be abel to think in properties. Because I knew in 1998 that this is needed to understand audio. 2,5 years ago I started to do vision the same way. It give the same endresults. Which is superior to anything.


The 1980 trial and error world you life in is a very limited world. First you need to understand that before you can make any good choice. All the decisions you wil make, will only get you access to a very limited level of each loudspeasker you will buy. 

The biggest problem of trial and error is the fact you you can only use a limited level in quality of what the loudspeaker is capable of. Tru-Fi proofs over and over again how much more effective it is.

When I let a new client audition a Tru-Fi system with his own music, they directly understand how much more effective a Tru-Fi system is compared to their trial and error system at home. 

When I see how people spend their money on a system I can understand and read that they are not able to use their money the best way. This is why I invited Audioquest to proof how much more effective we can use all their cables.

When you can think and work in properties you will always use each single part in any system so much more effective.


English is not my language. And I write down what I think. The english text which we use for the website are being grammatically adjusted by a person who is exeptional in the english language.

At the end you undersrand what I write. I seldom write back what i wrote overhere. I do not have time for that. Sometimes I make some time for it. It is fun.

Ofcourse I understand that the things I write can be F. irritating. This is more due to the fact that they cannot use it how we can use it.

I hope that you will understand that trial and error is very ineffective. All my clients now understand that it has no foundation. Like they will never do audio by trial and error again. They all know how limited the system was they owned before.

We are discussing now how we will use Tru-Fi for as many other people as possible. The people I spoke(who also work in audio) with all agree that audio needs to change.They all can see that the market is getting smaller each single year.

Trial and error will not solve this. I even think that trial and error is one of the biggest reasons why audio is having a hard time. When we meet new clients their systems are so poor. And they money they spend on it, never will be worth it.

I see no change by trial and error that people will get value for money. The facts proof over and over again that these systems are not that good. Many new clients use their systems not that often anymore,

This can be explained on how our emotion works. Tru-Fi brings these people to a world they never experienced before. They only listened to systems which are 2D in over 99%. And which miss even more different properties of sound.

No audiosystem in the world what is incomplete will ever be able to create enough emotion that you want to use your system for many hours each single day.
It does not change, you still all focus on products. The truth has nothing to do with spam. You still need to learn to look further. Sound will always proof and tell the truth. No one can change that.

The loudspeaker you own is the last and most important part in your system. From here you will hear your music you want to play. When you cannot read the loudspeaker you have no idea which amps, sources, cables, conditioners etc you need to connect.

What you do it you connect an amp, source, cables and conditioners on it and you hope for the best. But the truth is, you still have no idea what you connect. Based on the fact that you still have no idea what the properties are of each part in your system.

This is what most people do not want to read. So they say to eachother it is spam. The fact remains that you still connect each part by gambling. And when you dare to say it is different . Just explain why you make your decisions..........

The Blade and Reference still own their properties. This cannot be changed. Not by you and not by Kef. It will stay as it is. Even in the most ideal situation you still cannot reveal and play all the different properties of sound.

But.......trial and error systems will be connected to the Kef Blade. Kef Reference and also to the PL-500 II. At the end they still are only able to use a very limited level of the potential they own. People make the same mistake over and over again.

And again they do not want to read this. So the people who have the insight of a child will make remarks that it is only a story told by Bo. But they forget one important thing. Tru-Fi can proof easily and even for them that it is superior to their trial and error decisions. The decisions they will make all there life will never have any kind of foundation.

Based on the fact that they only can listen to the endresult of connecting all the parts togheter. And never in there life they will understand what the properties are of each individual part in their system. Tru-Fi can proof how limited the endresult is of all their choices. When you create a system by Tru-Fi even for their loudspeakers. It will outperfrom and proof how silly their choices where they made.

And again this is not what you want to read. You can write down whatever you want. It will never make any change. Your systems will be and stay trial and error systems. Trial and error only can create and reach a limited level in result.

Based on the fact that you will never understand why the sound and stage is what your system is playing. You only can chnage parts in your system by gambling. You disconnect for example a cable and replace it by another.

But you still have no F. idea which properties you take out and which you bring in. This is why you will never be abel to control and understand each decision you make.

I did discus this with many different people who also work in audio for a long time. And they all agreed that their decions are taken by hoping for better. No one could describe the properties of the part they took out and of the part they brought in.

After this they understood that the way they do audio lacks any kind of foundation. And again this is not what you want to read. But this is the truth. And Tru-Fi can proof it. And we have done this many times. And there was not even one person who was able to explain how he founds his system.

So again.......just write and explain how you make your decisions by creating your audiosystem. And why you it this way. ........


I told you how I work, many people who work in audio told me all that they have no real foundation. This also counts for all the peole who has audio as a hobby. It is all being created by gambling.

You want to believe that trial and error is the best way to create your own audiosystem. But the facts proof that trial and error is one big farce. The facts proof that each person will always choose blind that system what creates a higher level in emotion.

No one will choose blind any incomplete system. Our emotion works the same way. We only have different tastes in music. But at the end sound and music still owns it’s properties. And this cannot be changed by any person.

That is why I advice to read about the human emotion. And how music works on our emotion. You will understand and learn it yourself. We are only talking about facts and things that can be explained without any difficulty.

When I would not have listened a lot to real live music in small settings I would never be able to understand how big they are in proportion. And how big the diversity (layering) is in sound.

That is why I will use conservatorium students to play real instruments. So you hear them first in real and after that played by a Tru-Fi system. When you use the same music, it is very easy to understand how big the differences are between an incomplete trial and error system vs a Tru-Fi system who can reveal all the details and layers of the same recording.

Audio is shootout all over the world. You can compare it yourself. And all people will choose that system what can touch their emotion the most. That is why it is interesting for each person to read about the human emotion.






Sound is being formed by different properties. When an audiosystem can reveal all the different properties of sound it will create a more intense and emotional feeling than when you use an audiosystem that lacks different properties.

A client of mine owns the B&W804D3. I explained him that it can only build one meter in stage depth. He uses Accuphase what in all tests we did also showed that it can build about 1 meter of stage depth. This is what we call a hifi stereo parameter. The Platinum loudspeakers are able to create 5-7 meters of stage depth.

This is what you want and need in any highend system. When you are not able to create a huge deep and wide stage you are not even allowed to use the word highend. Based on the fact that humans can hear sound in a 3-dimensional spectrum. I think that a stunning holographic 3D stage makes listening to music so much more addictive and intense.

In 9 years of time I brought many people from a 2D system to a 3D system. And they all react the same way. They use their system so much more. And I gave them other properties of sound they also did not own

This new client bought a Lumin D2 with our Pro modification about 6 weeks ago. I did send him to a shop to audition both his loudspeaker and the PL-200 II. I wanted to make clear that the PL-200 II in a trial and error system is so much different than in a Tru-Fi world.

The system did not have any level in depth he said during the demo of both B&W804D3 and PL-200 II. He was rather dissapointed in both demoes. The day after I did send him to a client who lives not that far away from him. He owns a PL-200 II set in a Tru-Fi system with a Lumin and Pro modification.

This client is a musician in a band and plays and owns many acoustic and electric guitars. He is more serious into audio for about 5 years of time. And he visits shows and also visited different audioshops in the last 5 years of time.

He wrote me a nice story about his experiences during the PL-200 II and the Tru-Fi system. Later that day he phoned me as well. It was the best system he ever auditioned. He said; in a few seconds you already know that this is a different world.

He was stunned that the same PL-200 II had become a totally different loudspeaker than the day before in the audioshop. He was amazed how much better this loudspeaker was compared to his B&W 804D3. For the first time he could hear diversity in height. And mann this make a huge difference in how the music effects you. He could hear so much more details and information of his own music.

When he will have used his new Tru-Fi system and the PL-200 II he will write a review about his experiences. I will send the link overhere. He never experienced music this palpable and diverse in sound. It made his music so much more attractive he said. That same day he bought the PL-200 II and a Tru-Fi system.

He understood directly what audio does to your emotion and feelings when your music is being played by all the different properties of sound. You only can create an audiosystem what is able to reveal all the different properties of sound when each part in that system owns all the different properties of sound.

Because most brands and products cannot reveal all these different properties of sound. We only use and sell products who can reveal all the different properties of sound. This way we can outperform any other competitor easily. Each person wants the most intense and emotional system. Based on the fact that our emotion works this way.






No I am not a robot. But....... we use very high tech tools of over 7000 dollar when we install audio. Most people in audio still think it is 1980. And we work at 0.25 millimeter precision.

I think we life in a different world and are far ahead of what we call the limited trial and error world. I also call it the 1980 audio world. Because many still do audio at the same way as we did in 1980. But there are so much better tools and options to create a superior level these days

People have no idea how extreme they limit themselves by trial and error audio. The other problem is the lack in knowledge and insight regarding the acoustics, smog, magnetism and high frequent noise. Trial and error will only give you access to a very limited part of each individual component in your system.

That is why money will never solve it. The biggest problem in audio is the lack in insight and knowledge. Trial and error proofs how ineffective audio is being done. And it also proofs that people have no idea about the human emotion and also not about the properties of sound.

This proofs that they do not understand sound. But when you want to understand audio you need to understand the properties of sound first. Like you need to understand the acoustics and other parts like smog, magnetism and high frequent noise who all negatively influences the sound and stage.

Audio is done by random order and people have no real foundation. This is the main reason why most systems are not that good. Because they are not able to create a lot of emotion during listening. This is caused by the lack of properties of sound which are missing. When you add these properties which are missing, you see how different the same people react to the same music.

They all have no F. idea what sound is and which properties they use. It is pure gambling. This is audio done at the level of a child. Based on the fact that they have no idea what they do. Children have a lot less experience compared to adults and they will face many situations for the first time where they have no idea why it is as it is.

This counts for audio as well. They all have no idea why the sound and stage of their system is what they hear. This is needed to have any idea why you are hearing the sound and stage as it is. Trial and error will never make you understand your system. It will be a gambling system untill you die. And yess I understand that this is not the thing you would like to hear. But this is the truth and you need to learn to look further.....

You only can understand things you do not know when you do it differently. Trial and error will never give you any idea what the F. you are doing. This is a fact and I talked about this with many people in audio for many times. They all agreed that they do audio by gambling.

This means that they never thought about how to guide and understand audio and music. The 3th of july 1998 I had a mindset and I wanted to know why each loudspeaker is sounding so different than another does. I spend thousands of hours and tests to learn to think in properties of sound.

And you know why? Because I was aware that this is the only way to understand audio. But is looks like the whole world has been sleeping in the last 20 years. And the facts proof over and over again that they all do audio by trial and error. To be honest this is audio at the level of a child.

I confronted many people in audio with this phrase. And the most silly thing is that they all agreed that it lacks any kind of real foundation. That is why I ask it again..........

Tell me how you found your decisions regarding the choices how you select and create your audiosystem?
The PL-300 II is in a Tru-Fi world where it reveals all the details and different properties of sound a superior loudspeaker to the Kef Reference. But.......in a trial and error system there are different rules and a totally different outcome.

You only will have an idea what the PL-300 II is capable of when you created an audiosystem what can reveal all the different properties of sound. And that the system is fully adapted regarding the acoustics, smog, magnetism and high frequent noise.

The truth is that the PL-300 II is demoed in a trial and error system. This will never give you an idea what the PL-300 II can offer in a Tru-Fi world. What you all hear is your truth. And this is what you all believe in.

But your truth is being formed by the systems you auditioned. This makes you think what the quality is of the product. Let me say this. When you listen to the same loudspeakers in a Tru-Fi world the truth has become totally different.

It is not even comparable with any limited trial and error system. You enter a new world you even don’t even know it exist. Because your truth is the trial and error world. This is a world without understanding the properties of sound and all the different parts who negativly influences both sound and stage.




When you let people hear a stunning 3-dimensional holographic stage with even diversity in height, The Kef can’t even compete to this level. Maybe in your limited trial and error world you think it is good. It still does not own all the different properties of sound. When you are aware of how sound works and you know how to create it. You enter a world which makes the trial and error world sounds even silly and outdated.

When you all keep on doing audio by trial and error you will stay in a world what will never make you smile and proud each single time you listen to your system. When you are aware of all the different properties of sound your ideas about audio and music goes to a different level.

And the focus is only based on what you can create and bring to the max. Everything what is less or incomplete has no meaning. And you know why? Because it will never reach that level in emotion as those products and systems who can reveal it all.

Tru-Fi has nothing to do with any brand. It only makes clear if each individual product is able to create and reveal all the different properties of sound. These products will always outperform all incomplete products in a Tru-Fi world. And no one can change that. Because this is how our emotion works.
