I have just installed and listened to this on the 2L Greig Piano 192k downlaod. An hour ago, I listened t the same disc on my minimal audio PC with rme 9362. DAC is the UA2192 thru a passive attenuator.

The HiFace is KS only, which is good as it avoids this businesee of asio and its buffer size setting. The RME is also configured to play thru KS. Foobar 9.6.5 is being used.

This little device installs impeccably. It is not subject to interference as I am using in on my Vaio desktop with tons of services and the works by way of firewall and antivirus. My audio PC has nothing and just 1.5 Gb of WinXPSP2! The Vaio has has a standard power supply. As I hear this, I am not the web as well.

The impressive thing about the Hiface is that tempo and transparency are excellent (not as often with asio devices as one might think). Tonality is also very good. Imaging also. It is not as resolving as my RME system but very pleasant to listen to, with no hardshness or digital hash.

For e108, this device is better than the Musiland 01USD and much much better than the emu0404 and other 41/48 usb devices that I have heard. Marc, the vendor also answers every email (rare).

Technically, M2Tech says that the usb power bus is regulated and thus 'isolated'. The digital output looks fast with some ground bounce but jitter looks well controlled as the scope trace is very sharp. I can clearly hear the difference between a 50 Ohm coax coupler (to extend cable) and a 75 Ohm one.

There are already people trying to 'mod' it but I wouldn't bother as this sounds like an excellent plug and play unit about 3 in long only.
I shall try it on a laptop later.
