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.


audiofun
thanks as well great review, I've also been looking at a new phono stage and this has just risen to the top of my list.
Audiofun - Thanks for the tip on the LPS - Good find.  In my case it wasn't an option since me pre actually takes an 16V AC input - in the future, I might try one of these from Parts Express.

Robelvick- You still owe us a review too ;)

Thank you. Take a look about 3 posts up from you and you should see the link to the supply at partsexpress.

You are welcome, I am glad it was of help to you :) One other thing I failed to mention is that the iPhone 2 responds extremely well to vibrational treatments. I don't understand how something so low in weight can be so affected by what it sits on but I can easily hear it.

No problem with the questions. Obvious what may work in one system may not be right for another. I do have some great tube gear but the iPhono and iTube were both designed to be simpatico. I would at least try it. One fellow here took my advice and tried it and the email he sent me went something like "hooked iPhono 2 up to the iTube 2, mind #$%#$ blown".

Can't comment if Mr. Fremer likes it as much as his reference but  I do recall he placed the 1st gen iPhono in his system and allowed some of his audiophile buddies to listen while thinking the reference stage was playing. He stated that not one of them discerned anything was amiss and thought the sound was great as always. Well the iTube 2 is far superior to the 1st gen. I would suggest you try the iTube 2 with it, you have 60 days to play with it if ordered from Music Direct.

The iPhono 2 is a 15v device so you never have to worry about over-voltage as 15v is the limit of the supply I use/recommend. Switch Mode Power Supplies are inherently self regulating. So the iPower power supply is regulated itself. the linear supply I suggested is also regulated.
Audiofun, great review and agree I have the ifi Phono2 it's very nice.
 If I may ask, what was the LPS you are using?
Link?
Thanks for your response.  So, I take it that you install the iTube downstream from the iPhono(?)  Whatever works is fine, but I would choose/do choose to use good tube equipment in the first place.  I reckon that if I plug the iPhono2 into the AUX input of my full-function tube preamplifier, I would end up with a nice sounding device that has in effect two phono sections (one built-in plus the iPhono2), sans the iTube. In reading the Fremer review, I got the distinct impression that he was trying hard not to say that he liked the iPhono2 as much as his reference.

I also checked out the PS you use.  What voltage goes into the iPhono2? Do you know whether there is voltage regulation built into the iPhono2 box, or is the regulation normally contained in the SMPS? Sorry for all the questions.

Thank you for the compliment :)
I have been using the iTube in various ways since the first generation. When used as a true tube buffer, i.e. no gain, analog volume control disengaged no XBass or 3D all of which both work very well, the unit is truly transparent. With version 2 you can choose a SET, Classic or Push-Pull sound. I use the Classic. It does that weird thing where the tubes bring in the fluidity and continuousness as tubes can do so well. It does not (at least in Classic mode) give a tube-ee signature unless you want that, then one simply selects SET or PP mode.

It is akin to the finest tube gear where you lack all hardness which can be associated with some SS gear while not crossing over into that false lush tube sound. It is strange and hard to put in words but I am a stickler for neutrality NOT dryness or sterility or thinness. The iTube2 and the iPhono2 trip the night Fandango together :)

AMR owns iFi.
Audiofun, Thank you for the well written and "intelligent" review.  While I was already aware of the iPhono2 and have recommended it to others on a budget, because of Fremer's praise for it, I was not aware of the iTube2.  Just now, I Googled it, and I find that it is a small box designed to add various sorts of "tube-i-ness" to systems largely composed of solid state devices.  It's a veritable audio Swiss Army knife. So, how are you using it?  I am always suspicious of such devices and the ideas behind them.

Also, is there some connection between iFi products and AMR?
Thanks, again.
Greg:

Concerning the form factor, yeah its not ideal but it is very functional and allows iFi to maintain the same casing thus saving us money as they don't have to tool up for a different design. I just simply place my unit behind other gear on the rack. I don't need to see it :)
Greg:You are welcome. I really appreciate it when people take time to earnestly review pieces that I may be interested in purchasing. For instance, I have been scouring the web for any reviews of the Audio Technica ART1000 MC direct power cartridge to help me make an informed decision. Finally found a personal blog in which the gentleman did an excellent job describing the properties and sonic signature of the cartridge. His information has helped me immensely in my decision making process.

I use these supplies from Parts Express (make sure you change the fuse to something other than the stock glass fuse and you may want to disable the internal fan) "http://www.parts-express.com/pyramid-ps26kx-power-supply-6-15-vdc-22a--120-548"
Audiofun - Thanks a lot for the review.  Another member here picked one up recently and I've been hoping that someone on this forum would post more details about it.

I've been on the fence about this unit, not based on the reviews (which are excellent) but I'm struggling with the form factor - I know that its design is in keeping with their overall design language, but it is quite polarizing you must admit.

I think that I'm probably going to end up getting one of these and gut it straight out of the box and build it into a more "rack-friendly" chassis with all the I/O on the rear.  If I go that route, I'll also try to pack in a LPS at the same time.  I know this will void my warranty, but hey, that's just me.

Where are you getting your LPS?  I bought one for my current Pre from Swagman Labs in Hong Kong, at it's a really nice unit for the price.  Even with the custom chassis, necessary part and LPS, I still think it will be well under $1K which is totally reasonable for the level of performance that you describe.

Thanks again for the write-up
