And you are right we should probably go back to discussing usb converters

BTW, I have found this article on 6 moons website: 6moons audio reviews: High Resolution Technologies Streamer Pro It seems that HRT has developped some intersting async drivers.
Looks like the HRTs just have a single 48khz multiple type clock, no RBCD clock.

Tamahome77, have a look at my web-site https://sites.google.com/site/hifacemods/ for options
Thanks jkeny! I will let you know as soon as it gets here.

By the way, your website doesn't seem to include the last option you told me about

You are right, there seems to be no mention of a 44.1 multiple clock. It is weird that they are working on getting 384K on usb while it will be more useful to get a true audio clock at 44.1K... But I guess it easier to sell higher bitrates than higher quality at the more common 44.1K

No it doesn't list it yet - I have to work out some details/options first

Jkeny's modded hiface

I received this morning Jkeny's modded hiface along with the special usb cable and other stuff as well. I haven't had a chance to listen to it but it looks very nice

I will post my preliminary finding later on today, however, I won't go into much details until I receive back my stock hiface which is on its way back from m2tech (it was sent last week, so it shouldn't take much longer to get here).

I have also received the dac19dsp yesterday. From the preliminary listening impresions, it seems to be less sensitive to transports than my other DACs. So I will try the modded hiface on a few DACs to see how much improvements it brings on different dacs.

Nice & timely, slim.

Looking forward to your impressions.

My first impressions about the modded hiface are as follow:

I was planning to try Jkeny's modded hiface with a few different DACs. Since I just received the dac19dsp 2 days ago, I tried it with both the Musiland and the Teralink X2 and heard a smaller difference than usual (its dsp is supposed to have good jitter rejection). So I wasn't expecting much difference.

So my first trial was to remove the Teralink-X2 (that I preferred over the Musiland) from the chain and replaced it with jkeny's modded hiface. The chain was as follow:
Jkeny's Hiface - Oyaide BNC - DAC19DSP

I was totally floored by what I heard. The improvement was real and big compared to the other converters. What impressed more about the modded hiface vs. the other converters is that the modded hiface made everything sound real while the others struggled at various degrees to portray a poor copy of the real thing.
I just didn't have the strength/will yesterday night to switch to another dac to confirm my findings. I was able to just sit back and listen to the music without analyzing it ... which is a rare thing for me.

These are only my preliminary findings. I will wait a few days before posting a full review of jkeny's modded hiface (and comparing it to the stock hiface). However, since jkeny has done such a good job, I couldn't keep quiet about it.

Good job John!

Thanks slim
Told you all that it was a huge leap in SQ As slim has said & I've said all along - it's not one of these improvements that needs A/B testing to ascertain if it's better, it is immediately recognised as clearly better. High-end sound for little money.

BTW. if anybody needs to be convinced about the sound of lower jitter, this is proof . What does low jitter sound like? Expensive analogue

Yes, that last sentence pretty much sums it up!

Best part is anyone who can solder can do this mod, all the details are on diyaudio. I trust your ears enough to say we are talking about serious transport performance available to the masses for under $230. Meaning put your $20k transport for sale in an antique shop I think computer audio has finally come of age, been a long wait hasn't it? Excuse me I need to finally order me a Hiface.

Care to speculate how much better it is than a basic HiFace?

I agree, there is no reason today to spend insane amount of money on $20k belt driven transports. My guess is that a modded hiface with supercloks will put those ultra expensive CD transports to shame. That explains perhaps why Empirical Audio, for example, abandoned modding CD players and focused its efforts on the PC transport side.

BTW, regal, are you going to do the mods yourself or ask jkeny do it for you?

Sorry, I prefer not go into too much details at this point as I still have a lot listening and trial with different DACs to do. I will write a detailed review (with comparisons) in the next few days.
For instance, it is the first time I can clearly hear an improvement of native 24/96 over 16/44.1. Before, I could hardly distinguish properly upsampled 16/44 to 24/96 from the native 24/96. I really had to concentrate to hear any difference. However, now I can clearly hear the difference and it is pretty big. However, I have to try different combinations to determine the contribution of the transport into the increase in resolution.

The only thing I can say with confidence right now is that when the modded hiface is paired with the dac19dsp, it gave me the best sonic experience in my system so far. Sorry that I couldn't give a more direct answer at this point.

I'll DIY, I'm pretty good with a soldering iron even soldered in a few SMD PCM1704's. But I appreciate what jkeny is doing for those without soldering skills.

I agree, he made a nice contribution to the head-fi community by sharing his mods.

Slim.a, when you A/B the modded HiFace with the stock one, can you pleeeeaaase try it removing the battery of your laptop and plugging the laptop directly in your AC power conditionner. I also heard significant improvements while doing so with the stock HiFace. If the modded HiFace still hold its own and show clear improvement in this set up, I should be all for it. Thanks.
