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.

Dear @chakster / @audiofun : I know you in this phono stage regards and I can say you have not any agenda vs iFI productos as OP could think.

audiofun have really in deep " seed "/stycky on AMR/iFI products, this is something that makes no common sense for me if we take the very " high pedigree " he has as a music lover, audiophile and experienced engineering.

Obviously that each one of us have different target in our home audio system/room overall set-up, that mine is to stay truer to the recording.

From this point of view/target neither ( PH-77/iPhono2/SPL. ) can acomplish that target.

The more expensive PH77 and other that be an hybrid active device, that per sé precludes the target achievement, fail in a " shame " way ( for a 10K+ price tag. ) to meet the main PS characteristic ( other than gain. ) that’s to has an inverse RIAA eq. curve with at least no more than 0.1db deviation from 20hz to 20khz ( any decent low price PS does it. ).

This megabuck unit comes with specs that says it has a way high swing of 0.6dbs ! ! and its little SS brother a high 0.4dbs. Btw, the PH77 measured even worst than that manufacturer spec. Incredible for say the least and that was only for the standard RIAA but those gentlemans tooks its time ( marketing. ) to design its units with other over 20 curve alternatives even one that they " invented " because it never existed: the DMM !, go figure.

The AMR unit and the iPhono2 both are designed and marketed to a price point and with the 77 things goes beyond price point because the design has not the caliber of those over 10K+ price tag.

If I remember and even that for very good reasons I don’t support tubes one hybrid unit that I have respect for its designer comes with a RIAA swing of only 0.14db. My unit measures swing is 0.02db and I know that some people do not like to speak about specs but it’s really important to know where we are stand up.

OP, I know that that is what you like, it’s what fulfill your needs. Good for you.

Btw, that iFI TubeState trade mark is a signal manipulation it does not matters what you or otehr gentlemans can think, for me is a manipulation: iFI says in that way in its site as you can read in the link I posted.

No, my unit design has not SIGNATURE and was not designed looking for some kind of sound as you could think.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.


@audiofun   """  uses a discrete circuit that deliberately models the way tubes amplify audio. The TubeState creates a warm, spacious and...."""

THAT DELIBERATELY MODELS THE WAY TUBES..... again: DELIBERATELY and you said it was not a signal manipulation?

How is that?.

Puzzling iphono2!  I swapped cartridges a couple times changing settings as required for gain & load.  On the third attempt, no sound and I could not find the reason.  Finally turned off the iphono2 for 30 minutes to cool down then restarted and had sound.  I don't get it.

Also, it ran hot all day into the evening when my extended listening session ended.   I checked early this AM and the darn thing was barely warm and still is.   I don't get this either.

I reported the hot issue with iFi and the tech support guy said to return it.  I'm not doing that yet because I want to observe what happens over the next couple days.  Besides I already have about 20 hours use and it sounds pretty amazing.  

Are these two issues mentioned, normal behavior or do you believe I have a problematic unit?  I'll appreciate your advice.

Regards,
Doug Olsen

Raul:
Man your going to burst a blood vessel. 
Wrong again, the PH77 was $12k and with my Bendix and MU 6900 tubes more like $14k. I'm going to listen to my shame of a phono stage :) get some help

dougolsen:

i have not not seen that behavior. I'd take them up on the offer if you see this behavior again. 
dougolsen:

just a thought. I've never made configurtion changes with the unit powered up. Not saying you did, but if you did I don't know how the stage would behave.
