I think (but I could be wrong) that latency and buffer size are 2 different things. For the best playback quality, latency should be set as low as possible before getting crackles and pops, and the buffer size (of the file) should be set as high as possible. There are even players that buffer the whole file before playing it back.

You must be talking about additional latency delay settings in ASIO4ALL.
With KS/ASIO (at least with foobar20000) bigger buffer translates into higher latency, ASIO4ALL just lets you adjust playback latency to match your other devices, like recording mixer for instance.

BTW, if anyone interested, with SoX resampler I am getting occasional crackles/glitches when upsampling to 24/192 to HiFace. Guess the algorithm/software still needs some work. Without DSP in place everything is nice and dandy.

Sorry for the mix up, the "buffer length" of the hiface Kernel Streaming settings was so big (1000ms) that I thought it didn't relate to the same thing as the latency you can set with the EMU and Musiland. Indeed, with the EMU 0404 usb and Musiland native asio drivers, you can go as low as 2ms for the EMU and 5ms for the Musiland (using their control panel) for the latency settings.
I will try to experiment later on to see how low I can set the "buffer length" in KS before I start having crackles/glitches.

Edit --
By the way, I did most of my listening with the hiface/KS with default buffer setting at 1000ms. And with asio4all I lowered the asio buffer setting to 256 cycles (which I assume is the equivalent of what is called "latency" by emu and other asio sound cards).
Also, it seems that the "full file buffering" setting on foobar 0.8.3 only works for network drives and slow devices. So I guess this is the kind of buffer worth maximizing.

On my Foobar Version 0.9.6.9 "full file buffering" works on files stored on the internal HDD - I haven't tried it with external "slow" devices though.

Thanks for the info jkeny, I looked quickly for it ("full file buffering") on foobar 0.9.6.4 and I couldn't find it. I should look harder

Anyway, I have just went to foobar website and I found out there is finally a v1 (still in beta stage) version. Anyone tried it ?

Look under Advance in Playback. You need to enter the max amount of kB that you want to buffer.

The Mac Driver 1.03 (first release) for the hiFace has been released, and is available for download on the M2Tech site. It's stable.

Post delivered my Hiface today. Now i´m listening music through this small interface and i must say i´m happy with it.

I ordered it mainly due my requirement of hi-resolution 24/96-192khz playback. My previous TeralinkX as you know from slim.a review is capable only 16/48khz playback.

Hiface is really pretty small. Looks similar to flashdisk. But sound is big :-) In direct comparison to TeralinkX there is no day and night difference in terms of sound quality. BUT... yes there is difference. M2Tech Hiface seems to be better than TeralinkX in some kind of low level detail. Bass is very slightly tighter and maybe has got little greater impact. Soundstage seems to be wider. Don´t forget that everything is really very slight diferrence. Changing USB/Spdif converter to DAC is only something like final icing of cake in terms of sound quality in my opinion. But maybe my digital cable from Blue Jeans Cables (Belden 1694A) is not extra resolving and there should be bigger difference between transports with another cables.

Playback of hi-res files is really without problems. I like also that there are no pops and crackles during playback. And of course, instalation of driver was very easy. I played music in five minutes from unpacking Hiface :-) I´m using Win Vista.

EDIT// After more listening i can write there is definitive upgrade in sound quality in comparison with TeralinkX. Bass is deeper, dynamics is better and sound is somewhat faster.

I appreciate the thoroughness of this thread...very analytic with excellent supporting detail. Thanks, everyone!

OK time for me as well:

My setup apart from the sig gear is Windows 7 64bit using Foobar with FLAC's extracted via EAC. I am using a Blue Jeans Cable digital interconnect 1m long. Musiland is running the 1.0.0.7 driver

Firstly some of the negatives with the Hiface:

It sticks a long way out of the back of my PC (I don't want to use the front ports since the wires to them go through the PC) especially after adding the fairly stiff BJC cable.

I cannot use the USB port adjacent to the Hiface any more.

Now onto the software

I installed 1.02 drivers which went without a hitch but it does not show as a device in Audio only device manager. You must also download the Kernel streaming component for Foobar. You cannot as yet use this in Media Monkey. Foobar is slightly unresponsive when using the Hiface (though not with the Musiland 01 USD)

How does it sound ?
The 01 USD and Hiface are similar but the Hiface is definitely more resolving - you can hear this at the beginning of EVA Cassidy's People get ready especially on the cymbals. The guitar on Clapton's Tears in Heaven sounds less veiled on the Hiface.
Bass is similar in quantity on both but the Hiface seems better controlled.
On Creed - A thousand faces the Hiface was more coherent and airy when the track got busy.

I did my listening with HF-2's

I shall be keeping the Hiface

USB Extension cable?

I actually ordered a second unit for my office rig.

- With the latest drivers, what is the preferred playback bit-depth settings, 24 or 32bit
- Do you see it as an audio device in Vista 64bit, I can only see it in device manager, not in control panel Sound configuration. In foobar2000 Playback selection it's only available as KS: hiface Kernel Streaming, although 1.02 driver supposed to support DS as well, guess it's somehow related to the fact I can't see it as audio card in Windows.

Thanks
What everyone else experience with device registration as an audio card, please specify your OS?

that would kind of defeat the advantage of not having to use a usb cable, which can only make matters worse.

André, BTW the hiFace outputs a 32bit/192kHz signal on a Mac and would sound great with your NSD 192 MKII.
I don't think you'll find many converters at this price out puting this kind of signal.
