Experience with Mach2 Music Server?

Tvad - I assume you mean USB to s/pdif - I haven't heard the M2Tech HiFace, although I know they it appeared to have some performance issues when it was initially rolled out. I've heard very good things about the Blue Circle USB Thingee when used as a USB-to-spdif converter. A pricier option would be the Bel Canto 24/95 USB link.

Thanks for reminding me about that unit.

I'm currently using a Blue Circle USB Thingee and have owned a M2tech HiFace and to my ears, in my system, I find the Blue Circle superior. It had a more organic presentation. I found the Hiface slightly tipped up in the high frequencies which eventually I found tiring. The Blue Circle is also more accurate in terms of instrument timbre.

One drawback to the Blue Circle Thingee is that its limited to 16/44.1 - Blue Circle does make a pricier model called the USB Tunnel, which handles up to 24/96 I believe.
Another issue for me with the HIFace was that when I matched movies on my Mac Mini there was an lag in the audio which I could never solve. M2Tech acknowledged this and basically said the only fix was to use dvd software which could adjust for this. Not sure if this is relevant to you but I thought I would throw it out there.

Good luck in your search. I recently dove into the whole computer/audio world with a Mac Mini/Pure Music and USB thingee and couldn't be happier.

If I already have an 1 TB external hard drive with 2000 Cd's, will the Mach 2 work with this hard drive?
Or do I have to re-rip again?

Thanks for the info Tooter.

I noticed John Kenny suggests an attenuator for use with the HiFace, and I wonder if this is in response to the tipped up presentation you heard in the high frequencies?

What DAC are you using?
