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.

I enjoy Hans Zimmer as well, Interstellar is a great album.

I may have to try a linear power supply now.
I will check out Interstellar. I also have "Hans Zimmer - The Classics" and some of the theme music from Interstellar is on this album. 

You're in for a surprise, shock when and if you add a LPS.
Last week a friend gave me iPhono2 and on a weekend i’ve been able to check it out in my system with various cartridges (MM and MC). I decided to post it here before i will forget everything.

Luckily there was no issue with power supply i’ve been woried about about in my previous posts above. The size of the iPhono2 is even smaller than i expected, the RCA sockets are too close to each other, so maybe not the best for some of the bold RCAs like the Xsadow, but was ok for my WBT 0114, Eichman Bullet and LoveCraft RCAs.

**** **** My system is ... **** ****

2 x Luxman PD-444 turntables with SAEC SS-300 mats on one of them.

**** **** To make is short (about iPhono2 with MM): **** ****
I was not impressed by the sound of iPhono2 with MM cartridges, it was quiet, fast and dynamic, but a way too bright. I found all that switches useless, the RIAA is nothing but a tone control and has nothing to do with reality (as pointed by M.Fremer in his review), so i set up standard riaa curve. The capacitance load does not change much to my ears. The unfoirtunately there is no resistance load for MM cartridges which is far more important, so 47k Ohm is default setting.

Grace F-14 LC-OFC sound far more superior with 100k ohm load with JLTi phono stage. The bass impact was far more superior with WLM Phonata Reference (also with 100k ohm Vishay load resistors). Both WLM and JLTi have more weights and overall are much more comfortable than bright iPhono2 with the MM carts.

iPhono2 is better than Grado PH-1 phono stages, they are in the same price category, the Grado was $500 new, but i have changed load resistors to Vishay Naked Foil 100k instead of 47k.

Grace recommended 47-100k Ohm load for their cartridges btw.

I Would recommend JLTi for those who prefer MM cartridges, compared to iPhono2, because of the limited default 47k Ohm standard on iPhono2.

**** **** Now about iPhono2 with MC (Good news): **** ****
The iPhono2 was great with my Ortofon SPU Royal G mkII LOMC cartridge! Shockingly great for its price. I was very impressed about the sound quality, details, soundstage.

However both of my LOMC carts that worked well with iPhono2 were better with Luxman SUT + JLTi MM phono. Especially in the lower register. But the price of this combo (SUT and JLTi) is much higher. So i think for MC stage with high gain the iPhono2 is great!

But the iPhono2 does NOT work well with 0.05mV Ortofon MC2000 LOMC cartridge, 72dB gain is definitely not enough for this beast! If your cartridge is has such a low output then iPhono2 should be avoided. In fact even 1:30 Luxman silver SUT is not ideal for an Ortofon MC-2000, but much better than iPhono. The Fidelity-Research FR-7f is definitely better with SUT and my JLTi compared to iPhono2.

P.S. I will return the iPhono2 to my friend, it was nice to check it out for a few days with different cartridges. I do not have more time, but for me it’s clear. Don’t believe the hype! It is a good product, but even in this price category there are better products available with different features such as load resistors sockets. Personally i would NOT buy iPhono for MM cartridges, especially if your system is similar to mine, but it might work well for some great MC carts like the Ortofon SPU Royal G MKII (with this cartridge iPhono2 was great).
Chakster’s results with the Ortofon MC2000 driving the iPhono2, which supplies 72db of gain, were to be expected. As someone else noted above, the .05mV of the MC2000 would produce 0.2V output. If you connect the iPhono2 to a high-ish gain linestage (at least 10db or better yet 15-20db), then you’d have enough signal voltage to drive most amplifiers. 0.2V won’t get much out of an amplifier, although the cartridge output of .05mV is the measurement at a modest stylus velocity of 3.54 cm/sec (the old standard value, I assume since the cartridge is so old). During music, the stylus moves much faster much of the time (therefore producing more signal voltage than you might think), and sometimes an apparent mismatch between cartridge output and phono gain, like this one, can be surprisingly OK.

My phonoline stage produces well over 80db total gain (probably close to 90db) and handles the MC2000 with no fuss and no SUT. The MC2000 is a one of a kind weird duck, for sure, but worth the effort.
Maybe i will give up on this Ortofon MC2000, i have plenty of decent MM cartridges and some easy to use MC for my phono stages. My sample is mint condition in original package with everything included. MC2000 has lower output than my ex ZYX Premium 4D (that one was 0.24mV and dead quiet). So i'm open for offers for this beats.
