Review: Jkeny’s modified Hiface

^ Will do, although I plan not to post any impressions till complete burn in, and a good understanding of its effects are arrived at. Feel free to PM. 
 
Can someone post an alternate link for suitable ac/dc power supply? Unfortunately the seller listed at JK's site has a $25 min.

The mk3 is in with 4 hr on at the moment, and I think I can make a few quick comments before retiring.
 
- the mk3 improves transient performance---you can feel the attack of a solo violin in the foreground, as well as violins plucking in the back---its almost a visceral sensation
 
- the black background---in Hilary Hahn's Bach concerto no. 2, 2nd movement, there is a harpsichord lying low in the background following along with the rhythm---what the mk3 brings to the table is the attack and decay of the note at each light pluck of the string
 
There's a few other things going on that I could mention like detail and imaging, and with time there will be more for the discovering. To tell the truth there's nothing here to review, because the mk3 fits in so seamlessly, adding strength to the strengths of a pretty decent system.

I see you've built yourself quite a setup (transport, source, amp, headphones all very nice). You should be able to hear the improvement coming from other converters. Let us know how it turns out.

Thanks, I'll be posting impressions in time. With the additions of the GS1, Mk3, and RS1, I can say that I feel well grounded with this system. Its finally reached the point where I can focus next on an up-to-date totl headphone.

mk3 has arrived and charged!  OOTB this thing is miles ahead of the AGD DI - were not talking changing SPDIF cable maybe-yes-maybe-not different, this is literally on par with changing headphones, DBT proof changes.
I can only imagine if burn in improves things.  Very happy with this little box, it's worth every cent.

This is literally the most ridiculous statement I have ever read on Head-Fi, and that's saying a lot.

Hi
 
Any of you guys in the mood to run off some Audio DiffMaker files so you can see if what you appear to be hearing is really there???  Just asking.
 
Edit: 
 
What would be really cool would be if jkeny, who has access to each of his versions, would make some DiffMaker files to demonstrate the differences between  the MK1, MK2 and MK3. 
 
One would think that if the various versions are so audibly different, a diffMaker recording  or two, would go a long way, because they are reproducible by anyone with the gear.

Has anyone established if DiffMaker actually works? I want to know if it ever finds any differences.

I have a new Redwine HPA with a  minwatt tube replacement. With  Denon ah d7000 headphones the HPA is very clear, articulated, holographic and  natural sounding. I have been really enjoy this combo. Previously I was using a Apogee ensemble. Which was nice but it has been used primarily for recording music. I was using a stock usb cable with the HPA. Which sounded good as it is galvanic  isolated. But I came down with the audiophile bug and wanted and even better sound. I was looking at a locus axis usb cable, but decided a spdif converter would improve the sound more. It was also cheaper. When I first got my Hiface Mk 3, I plugged in my old  Sennheiser HD 280 pro's to burn in the unit. But to my utter disbelief this combo sounded better in a lot of ways, than the HPA with the Denon 7000's. This was without proper burn in! Don't misunderstand me. I greatly prefer in every way, the Denons over the Sennheiser HD 280 pro's. I kept this combo in place. Because I figured by waiting to put my good headphones in would be like getting another new toy. Boy was it! The mk3 is NOT subtle at all, it gave the HPA a huge improvement in sonic performance. Similar to drez's post, it's like changing the headphones or DAC, not a cable. The sound stage became even more 3D. Allowing a more accurate placement of instruments which were deeper and wider. It felt like a huge veil was lifted with a much blacker background. That I did not know that was there. As the HPA is quit black to begin with. Micro details within songs not only became more readily apparent but were clearly defined in space. The bass was tighter and much more articulated. The high end sounded extended and clearer, without grain. Cymbal began to sound as if you hearing them live, with proper attack and decay. Everything had more body and was richer . Bringing everything closer to that elusive  "REAL" sound. Anybody who does not believe a hiface mk3 makes a difference in sound, only needs to hear one! Well truthfully, in my experience I can only say with a Redwine HPA it will make a HUGE difference. Making a GREAT sounding unit even better!

Either the DAC he is using is bad or it's an exaggeration. I personally find differences between transports to be quite subtle. 



The former could be the case - I am using ESS9018 which I believe decodes the SPDIF data on-chip (I cant recall what oversampling it does etc).  We are also talking the difference between adaptive USB and asynchronous.  Or it could be that the DI is just really that inferior.  I can't personally say whether this is better or not to a stock hiface as I have not compared.  But the statement I made WRT magnitude of difference is definitely not an overstatement.  If one had adequate equipment and methodologies I am sure one should be able to measure a difference - but I don't have access to studio grade equipment.  What I can do, and have done is set up the mk3 and DI to run off separate computers into my DAC allowing easy A/B listening comparison, and from there the differences are easily discernable, not SPDIF cable swapping sort of guesswork.  A thick layer of sludge has been lifted.
