review iPhono 2


I must be slow as I could not find a link to place this as a review. 

So, I have written about the 1st gen iPhono in the past, comparing it to the very fine Coincident phonostage which I believe is about $6k. I preferred the iPhono but I could just as easily imagine someone else going for the Coincident unit. In that review I thought the Coincident had a better sustain, decay and bloom while the iPhono was hands down the winner in the prat department. The iPhono made my feet move, the Coincident, not so much.

Later on I added the iPower to the fray and the iPhono shored up the areas it lacked. As a former owner of the very very nice Graaf GM70 I was a bit surprised and dismayed when I finally received the iPhono and heard it once fully run-in. I would not have shelled out the thousands of dollars I paid for the GM70 and the vintage NOS tubs I purchased to make it sing, oh and the $1600 I had to spend on the Ortofon ST-80SE SUT to use with the MM inputs of the Graaf as I could not get it quiet enough to tolerate with the MC inputs. The very small $400 iPhono basically did everything the Graaf did (with the iPower that is).

My reference phonostage for the last few years (and probably many more to come) is the fabulous AMR PH77 and I’m running it with a set of Bendix 6900 tubes which elevates its performance even more than the already stellar stock configurations performance. In comparison to my PH77, I found the 1st gen iPhono to be a bit thin and during crescendos it could become a little ragged. Still, it remained in my arsenal as a handy and trusty back-up. The PH77 is of course tubed and as we tube owners know all too well, sometimes they fail and you are down for a while.

Compared to most phonostages I have heard, some of them costing up to $9k I found the 1st gen iPhono to be able to hold its own in some cases crazy as it may sound it was just plain better. I believe AMR intended the iPhono/iTube to be used in conjunction as a sort of baby AMR PH77 and I ran it that way for some time and yes, it does share that familial DNA when it comes to sonic signature.

Move forward some years and I have in my possession the iPhono2 and the iTube 2. To say that the iPhono 2 is better than its predecessor is far too simple a statement. Mr. Fremer thought it to be at least twice as good as the original. I would agree with his assessment. Out of the box with the included iPower is shows far more prowess in the areas of bass but otherwise is pretty close to the original. After about 20 hours a bit more fluidity begins to appear. Again at the 100 and about the 340 hour mark big jumps occur in the areas of fluidity and continuousness. When you get to 480 hours forget about it!

This thing sounds like it has a tube in it, and I don’t mean in that classic overly warm soft rose colored sound that I found so fantastic when I was new to high end audio. No, I am referring to a pellucid but meaty embodiment and rendering of the music. A sound one would immediately associate with MUCH costlier gear.

Most of my listening has been done with my second turntable system which is composed of a Technics SL-1200 GAE with a fully broken in Denon 103R on a LP Zupreme 15 gram headshell and my London Reference. The phono stage then feeds the iCan Pro (best pre I have heard and I have owned 2 MFA Ref units, the baby Ref and the full Ref), the Tube Research Labs GTP 2, and many more. I have had in my system for evaluation the Veloce (battery powered) the Allnic L3000 and many others. From the pre it goes to the custom active crossover and then to a Graaf Modena for the mids, a Harmonix Reimyo PAT777 for the Raal Ribbons and a pair of Acoustic Reality Thaumaturges ($25K when available) for the woofers. The speaker is called the Encore and is my own design. I simply got tired of paying for passive boxes made of MDF with wood screws going directly into the glued wood dust and sold for tens of thousands of dollars but I digress :)

The sound is at once flowing and dynamic. It grabs and holds my attention and really gets my foot tapping. The sound is MUCH more refined and fuller than the original iPhono with no hint of raggedness during large scale bombastic music. For instance it scales far more convincingly on some of the more challenging passages in Hans Zimmers wonderful soundtrack to Gladiator. The original could sound a bit blocky if you take my meaning. It did not have the ability to gracefully scale the mountain so to speak. The iPhono 2 does it with much more ease and refinement.

Here is where it gets interesting. As good as the iPhono 2 is out of the box and it is very very good (and especially after 340 hours or more) in fact far far better than the DS Audio optical cartridge system that I auditioned, it can be made to sound a good deal better. Now this is my own thing, the iFi line of SMPS’s are admittedly super quiet and much better than most SMPS such as the ones inside my apple gear, but I hate them ALL.

I do not like green eggs and.., ahem. Sorry, just flashed back to Dr. Seuss when I thought of my aversion to SMPS’s.

I mean I understand why they are used, efficient,  cheaper to ship and inherently regulated. But they still hurt the sound of my system. As an aside I am actually having a custom linear PS built for my SL-1200 GAE to replace the awful SMPS that Technics installed. So to the point, I replaced the iPower with a linear regulated lab grade power supply. I don’t like hyperbole so I offer none but the result was nothing short of breath taking. There is a great deal more that can be had from that little silver box with a good (and I do mean good) linear supply.

Next I added the iTube 2 to the fray. As I mentioned before AMR always sorta intended this combo to be a baby PH77 as was or may still be mentioned on the iFi site. How to put this; everything I have said about the iPhono 2 up to this point; multiply it by 2 times again. Now you have that sorta living presence that the performers are in your vicinity. Things are rounder, more palpable and it breathes much easier. Again I powered the iTube 2 with a linear supply along with the iCan Pro. Please don’t misunderstand me, I lived with these units powered via there very good SMPS’s for quite a while and they made beautiful music BUT I knew there was much more to be had.

Like Mr. Fremer (paraphrased) stated, to get better than the iPhono 2 you are going to have spend much more and you still may not surpass this unit. I auditioned a $16K current phono stage that people rave over and my ears tell me that it cannot compete with iPhono 2/ iTube 2 combination.  I will not call this a reference phono stage. It is great and I listen to it daily but I reserve titles like reference for the likes of Ypsilon, VDH Grail SB and my AMR PH77. The little combo does far more than I could have imagined. It capable of truly astounding musical reproduction on a grand scale.  

Remember to let it run in for at least 100 (and I suggest 300) hours before you really start to judge it but my guess is it won’t take most people that long to know that this is special gear designed by some super gifted engineers who also happen to actually be able to HEAR. Thanks for reading and I hope this helps someone make a decision one way or the other. Happy listening.

Raul, obviously you are writing about my tri-amped system.  I'm a degreed elec engineer so I think I can write with some authority when I say the iPhono is 100% solid state.  Concerning tubes and SS, they both can sound wonderful. My Acoustic Reality Thaumaturges are one of the finest amps I've ever heard and they are SS, but my Graafs (2x GM200 and a Modena) are flat out the finest sounding amplifiers I've ever heard.  I believe you when you say tri-amping didn't work for you. It certainly works in my system far far better than any passive system I've heard. I designed the speakers and the crossover. 

Different strokes for different folks :)
^^ well said @audiofun. I would also like to thank you for this meaty and pellucid comment in your original post:

I've been looking for those words but you found em... 
Dear @audiofun : I don’t said was not SS design but that the Ifi people are the " Carver " designers on that models. I said it’s a tricky design and any one can read what they explain about it’s trade mark: " Tube state ". Here is where appears the " Carver " signature. I hope you remember the Carver’s " anecdote.

I know that every single electronics tube system foundation owner are really proud on those tubes and sincerely I don't see why in 2017 any one that knows exactly how the live MUSIC in a near-field fashion sounds can be proud to own tubes. Makes no sense not only to be proud but still use that heavy limited technology that can't today honor MUSIC.

About the triamp or even forth one set up it’s not that " did not works for me ". I learned that even if we have a non bi-tri amp set up but using monoblok amplifiers it’s a must that both be matched in precise way on some operation main characteristics as: gain/sensitivity, damping factor, frequency response, distortion levels, slew rate, bias level, etc, etc. and I mean truly matched where one channel is a " mirror " of the other.

When we are using 3-4 different amplifiers each one has its own " signature " even if matched about what’s a " pain in the ass ".

I’m in favor of active speaker designs as ATC but but but .... and if if if ..these buts and ifs are a real trouble if we want to be nearer to the recording.

As lewm I don’t like to mnipulate the audio signal to even the " signature " because as he said it developed " colorations " that at the end are only additional distortion levels.

I think that due to your specific knowledge levels on that regards you can understand my take here it does not matters if you disagree. Could be controversial? maybe but I try very hard for years about even with four same ML 20.6, so I don’t have your specific knowledge level and maybe not your skill levels but I have in deep experiences on it.

Anyway , you are satisfied with and this is the important issue. I remember that I was satisfied with for years till...............


Regards and enjoy the MUSIC not DISTORTIONS,
R.




Dear Raul, I am not quite sure what you meant to say in your original post of 4/16 at 3:22 PM.  If you are saying that bipolar transistors are inherently superior to JFETs, MOSFETs, etc, then I have no dog in that fight.  I would favor whatever sounds closest to live music.  You might be interested to know that I once asked Stan Klyne if he could make any improvements in the design of the input stage of my Beveridge amplifiers, which is all solid state.  (He was interested in purchasing a pair of Beveridge speakers.) Mr Klyne's position was that there would be too much to do, because he would want to use all JFETs.  So, in the realm of solid state there appears to be a schism between those who prefer bipolar and those who prefer one or another type of FET. (I realize that MOSFETs are primarily used as output stage devices in amplifiers, not in phono or linestages.)  I know you respect the Klyne preamplifiers, and evidently they feature JFETs, as do many other solid state phono stages.  I also am not sure what you meant to say about my modified Atma-sphere MP1; I do use a bipolar transistor as the bottom half of the input dual-differential cascode, in the input of the phono section. No FETs anywhere.  Allen Wright used JFETs in his single-ended phono stages and bipolars in his fully balanced RTP phono stage.
