Talk but not walk?


Hi Guys

This isn't meant to start a fight, but it is important to on lookers. As a qualifier, I have my own audio forum where we report on audio issues as we empirically test them. It helps us short cut on theories and developing methods of listening. We have a wide range of systems and they are all over the world adding their experiences to the mix. Some are engineers, some are artist and others are audiophiles both new and old. One question I am almost always asked while I am visiting other forums, from some of my members and also members of the forum I am visiting is, why do so many HEA hobbyist talk theory without any, or very limited, empirical testing or experience?

I have been around empirical testing labs since I was a kid, and one thing that is certain is, you can always tell if someone is talking without walking. Right now on this forum there are easily 20 threads going on where folks are talking theory and there is absolutely no doubt to any of us who have actually done the testing needed, that the guy talking has never done the actual empirical testing themselves. I've seen this happen with HEA reviewers and designers and a ton of hobbyist. My question is this, why?

You would think that this hobby would be about listening and experience, so why are there so many myths created and why, in this hobby in particular, do people claim they know something without ever experimenting or being part of a team of empirical science folks. It's not that hard to setup a real empirical testing ground, so why don't we see this happen?

I'm not asking for peoples credentials, and I'm not asking to be trolled, I'm simply asking why talk and not walk? In many ways HEA is on pause while the rest of audio innovation is moving forward. I'm also not asking you guys to defend HEA, we've all heard it been there done it. What I'm asking is a very simple question in a hobby that is suppose to be based on "doing", why fake it?

thanks, be polite

Hookay...

It seems my very first reply to you in this thread remains as pertinent as ever.

Not doing the hobby is when someone speaks as if they have some knowledge on something yet they personally have never done it.


But you are casting a wide, disparaging net there. It’s one thing to say of a single subject being discussed "you haven’t personal experience with X." It’s another to cast this as "the hobby." People can be doing high end audio, doing "the hobby" just as much as you are, yet disagree on a subject. Someone could say "Well, Michael, I don’t put tuned wood blocks under my cables because I’m not convinced by your reasoning that it is efficacious." But simply voicing skepticism is NOT tantamount to "not doing the HOBBY." That person can, it should be obvious, still be quite engaged in the hobby of high end audio and their own system.

But your way with words doesn’t even allow for the idea that two audiophiles can be in "the hobby," yet disagree on some specific subject. This is the type of careless way with wording that, yet again, is problematic for good discourse.

Faking it is the same thing. They will make comments about a subject and yet have never really explored it.


Same problem here that I highlighted in my first post to you.

First...commenting on a proposed tweak (or whatever) IS a way of exploring it. If you suggest a tweak, and I ask "How does that work, exactly, and on what evidence are you basing this?" then that IS part of exploring the subject. A tweak first has to make some sense to someone in order to motivate putting money...or just time and effort...in to it.

Further, there are often times when someone can reasonably comment on a claim that they have not personally experimented with. I don’t have to have gone to the moon personally to argue it’s unreasonable to claim it’s made of cheese, and I don’t have to have tried using homeopathy to point to very good reasons that the claim is based on bunk. Quite a number of high end audio tweaks fall into a similar category, where one can point out the claims are suspect in nature, if not technically, and the vetting process unreliable.

So one way to be more clear on where you stand is to answer: Would YOU put me in the category of "not doing the hobby" or being a Faker?

Answering this would go a long way to clarifying your stance, and also showing how reasonable it is or not. (Your first reply to me suggested you put me in the "not doing/faking it" camp...but I’m looking for clarification).

The reason I asked you if you knew the difference between those two caps is so I could see how experienced you were with the sonic differences between audio pieces.


Again...you seem to extrapolate from isolated examples to imply an unjustified wider conclusion.

That I haven’t experience comparing those caps does not equate to my not being experienced "with the sonic differences between audio pieces." I’ve been in to high end audio, heavily, since the early 1990’s, and have been comparing audio devices with great fervor for decades.
So who are you to try to extrapolate from some simple capacitor example that this disqualifies me from be worthy of discussing with you audio differences?

Prof some people swear they can’t hear the differences between caps. That to me is a disqualifier for me to want to talk to them about the sound differences.

I didn’t make any such claim that they don’t sound different, right? But you went on to ignore my reply with just "thank you" and no reasoning or clarification beyond that.

Same goes for the ties snipped from the caps.


I haven’t declared that snipped caps don’t sound different. I’ve given reasons why I don’t just accept the claim at face value, and asked for more details explaining the purported phenomenon. That’s reasonable isn’t it? You see that’s different from declaring they don’t make a difference, right? And yet everything you write keeps implying my concerns are just trolling, and are not serious questions, and even though I keep explaining "I’m not saying it’s impossible" over and over, your replies keep referring to people who say "it’s impossible." I’ve simply been asking for you to interact with what I actually say, vs what seems to be some other version you have in your head that you keep responding to.

Fact is, the change did take place and Jay and others here who have gone and done this experiment while this thread was going on heard the difference and reported it to me. I’ve taken my time responding to you because I wanted to heard from folks who actually "Did" the experiment.


So this is a problem I keep pointing toward. Your OP made quite a deal about being empirical, and you referenced being scientific. ("why....do people claim they know something without ever experimenting or being part of a team of empirical science folks.")

But what I’ve seen from you isn’t very scientific at all. I’ve been asking the very questions someone thinking scientifically would ask:
What is your explanation, what makes your hypothesis plausible as a starting point for investigation. Have you measurable results to show?
And then, have you tested your hypothesis that the results are actually audible in ways that account for the relevant variables (e.g. bias, human imagination, etc)?

See there is a whole world of difference between simply "empirical experience" and being scientific. Flat earthers are basing their beliefs on their experience. But they aren’t being scientific.

If you were familiar with scientific empiricism, you’d recognize my questions as pertinent and in fact welcome them - scientists know they gain strength in their hypotheses insofar as they can stand up to skeptical scrutiny.

But you keep reacting like skepticism is a bad thing. More like it’s a buzz-kill when you just want to discuss your claims, and only talk of positive results unchallenged. Skepticism is just, apparently, a way to troll you.

Such an attitude is much more aligned with pseudo-science, or new age magical thinking or faith, rather than empirical rigor. So you should be able to see the grounds for skepticism here.

If you feel it’s fair to call people out for not "walking the walk" isn’t it fair to call you out for giving lip-service to science and empiricism, while not "walking the walk" by actually taking scientific rigor seriously in your methods, and in your responses?

Where the talk would come in is all these posts on this thread meant to derail or be a distraction. I would call all those with the intent to derail, troll or just old farts needing attention "fakes".


This just sounds like someone who won’t put up with any challenge to his claims.

Michael, please look again at your OP.

You did not make a thread about your tuning methods.

You made a thread specifically calling out some group of people for being fakes in this hobby. Not just that; people you claim are part of this forum. That’s what your entire OP is concerned with, from thread title to the last challenge to these people "why fake it?"

Did you honestly think you could just devote a thread to disparaging some group of people...and not have anyone challenge you on your claim? Like you can just gripe all you want about some subsection of people in this hobby and you expect only pats on the back and no pushback? Surely you can’t be that naive. And you even started with the understanding you would be raising hay by saying "you didn’t want to start a fight." But again, that’s like saying "I don’t want to cause any ill will - but some of you are fakes. Just don’t challenge me on that."

Numerous people have pointed out this problem in your OP, and in your follow up posts, so I don’t know why you refuse to listen to any criticism and keep blowing it all off, assuming the only reason anyone could pushback is if they are fakers or trolls.

Far from "de-railing" from the topic, I’ve been in fact KEEPING this thread on topic by asking you to back up and clarify the various claims in your OP. Trying to see whether I, or anyone else at all here, warrants your disparaging remarks. And probing your claims on empirical testing and it’s implications.

It seems you will only countenance on-topic remarks IF they support your claim and pat you on the back for calling out these purported fakes. But if someone challenges your claim...well they are of course the fakes and trolls you referred to. A perfectly circular type of response, more suited to religion than to someone truly empirically open or scientific.

For me this is a successful thread because listeners are "doing".


Which apparently means "doing your tuning stuff" and that’s "the hobby."

This smacks of self-important elitism, evangelism, not of egalitarian respect for other people to have their own approach.

I’m "doing" stuff all the time in the audio hobby. And I’d suggest literally everyone on and probably reading this thread is "doing" as well. But your stance continually suggests someone not doing your thing, or who voices any skepticism, isn’t "doing the hobby" or isn’t being empirically consistent, or is a faker or troll.

And that’s...to put it more politely than it deserves....not true or reasonable.

I didn’t come on this thread to "derail it" but rather appeal to you to clarify and substantiate your claims, and to helpfully suggest - being explicit that I was not accusing you of being malicious! - that creating a thread to disparage unnamed people was likely to be problematic.
And...it was. (And it’s not just me...many others have been trying to tell you this).


@grannyring 

However, why continue to derail the thread and waste our precious time as some of us would like to expand our knowledge here.


I believe you may have lost some perspective on the subject of this thread, grannyring.

Look at Michael's OP.   He did not start a thread along the lines of "ask me about my tuning methods" or "let's discuss tweaks and tuning.'

No.

It was a thread explicitly devoted to castigating certain audiophiles.  From the thread title, through the body of the text, to the last line challenging these people - "why fake it?" - it was a call out, to talk about fakers and a challenge to those "fakers."  

How could you reasonably expect this thread would not breed any acrimony, given the negative assessment of other people contained in the OP?

Anyone showing up to challenge Michael's claim IS keeping the thread on topic.  I've been asking Michael for examples to support his claim.  I've been asking if I fit the profile he's talking about.  I've been asking questions about the empiricism and science Michael appealed to in his OP.  I don't think anyone has been MORE on topic of the OP than I have.

Turning the thread in to a Michael Green tuning techniques thread would be making it off topic - he could start any other thread about that specifically.  And if that was in fact the motivation for Michael to make this thread, to evangelize again about his tuning methods, then the thread title and OP would have been deceptive on his part - a bait and switch, "trolling" with a negative post about other people in order to gain eyes to turn the subject to his tuning methods again.

I've at least done Michael the respect of trying to keep this on the topic he started, if that in fact was his motivation for this topic.


Constantly trying to put a negative spin on someone’s motive and methods is just not what these threads are meant for.


Again...did you even read Michael's OP?

He STARTED this thread via a NEGATIVE assessment of other people's motives and methods!   If someone isn't trying out his methods, and is calling upon other experience or resources other than simply trying his tweaks, then he's calling such people fakes.

But no one has to be a fake to voice reasonable skepticism about a claim.

It's fascinating that you so easily see negativity and suspect motivations in others, but everything MG posts is all roses and sunshine.

@theaudiotweak

The following applies to all material surfaces especially 2 or more
dissimilar materials of varied shapes. Adjusting the surface tension
changes the surface shear speed of the materials ..becoming either
separate,combined or somewhere in between. The result is more or less
interfering energy being transferred back and forth between these
surfaces in intimate contact or from the compressive world onto a
solid then becoming shear. So in many examples of using gucci caps
tied down to horrid materials made of sawdust and glue you will have
the sound of that cap altered for sure by the larger mass of the
material it is forced upon. The size and mass of the same substrate
will also give you a different result.The tie down material will also
become part of the sound of the cap. As we know vibration is all
around and cannot be isolated. We can make vibration a useful tool and
most pleasant. Just need to know the why and how..Tom ..
Star Sound Technologies and Tone Acoustics


Even if I take your explanation of resonance at face value...your follow up claims about the audibility of untied caps is very wanting. You make rather large, unsubstantiated leaps of logic.

The question remains: how much vibration is *actually* occurring in any component in question, or in the case of any cap, and then; does it have *audible* consequences.

Your whole explanation just begs the question by presuming what I’ve been asking you to argue for.

A common theme I find in the audiophile tweak world is that the tweaks - be they high end AC cables or whatever - come with a bunch of technospeak giving the air of technical respectability. But suddenly the technical claims are dropped when it actually comes to demonstrating the claims.

So for instance, there will be claims by a boutique AC cable manufacture based on technical claims about impedance, various types of noise to reduce, etc. Now, these are not phenomena they are pulling out of a hat. These things are measurable; that’s how the phenomena was detected and understood in the first place.

And then they talk about how their product addresses the technical issues (e.g. maintaining desirable impedance, rejecting undesirable noise etc). So it’s a technical hypothesis. But in high end audio products, it’s not JUST a hypothesis that the phenomena in question exists; it’s the hypothesis that the tweak, or product, under consideration produces AUDIBLE CHANGES in the output of a stereo system.

And the funny thing is, after all the techno speak by the manufacturer when you ask "Ok, can you show us measurements indicating the audio signal output has been altered in any way by the introduction of your product?" The answer typically boils down to "Why would we do that?"

It’s bizarre.

The claims are technical RIGHT UP to the point where the hypothesis should be validated...and then suddenly technical/engineering problems that can be measured...and then claimed to be fixed by the product...suddenly can't be measured, or don't need measured validation!   Such considerations suddenly disappear and it’s "don’t you hear the difference??"

This is the Big Red Flag in high end audio claims. Appeal to science and engineering all the way up to the point where you ask for measured results, and then suddenly it’s handed off to marketing.

So...bringing these concerns back to your explanation....

My questions would be:

In the case of an average electronic component - say a CD player sitting in my rack or whatever - how much vibration would the unit actually be undergoing? Have you measured this? I can tell you that, at least with my ipad seismometer app (obviously more crude than a professional device) it can easily measure vibration levels I can’t even feel. It registers no detectable vibration when simply sat on any of my components. Zero. And that’s a device *looking* to register vibration.

So right off the bat, this implies that components such as those in my house are, if they are undergoing any vibration, it is very, very low (or below the threshold of what I can feel and measure with my app).

Why should I expect such a low level of vibration to excite resonances, or to cause such havoc on capacitor tied to a circuit board, that this would alter the signal to an audible degree? (I have other reasons to be skeptical of your claims, which I’ll leave out for now).


Do you have measurements showing the average ambient vibration on a component? Do you have measurements showing this ambient vibration actually alters the values or performance of a tied vs untied cap? Those are pretty obvious questions, right?

Then do you have measurements from any output of an audio device that uses capacitors that indicates the audio signal would have changed? How did you measure, how did you test?

If only via listening tests, did you account for listener bias?


I ended my work day early with the hopes that I could experience what I did last night. Sure enough when I approached the door I could hear "Faith" playing on the inside. One thing was different when I walked inside from last night. There are three boxes at the entrance to MG's place. "what are those" Michael explained that every year or two he does a series of listening reviews on different groups of products. He gave me a list of last years components and this year he has switched from products like Accuphase and Bricasti to old school receivers and his Magnavox special CDP. I need to get back to listening.
This is a different hobby! How to describe the sound stage I've just heard is going to take some thinking through. One thing absolutely positively for sure I can tell you is I'm not going back.
