Mutec is a German company that primarily deals in the professional A/V sector, but they've recently started gaining traction with audiophiles.
I picked up both options to check them out, and some of the wilder sections of the Internet have been raving about these interfaces.
http://www.mutec-net.com/usbinterfaces.php
The MC-1.2 is a high-performance USB audio interface which converts from USB to AES3, AES3id and S/P-DIF signals, and vice versa.
The MC-3+ Smart Clock USB is setting a new benchmark for clocking technology and the reproduction of digital audio by uniquely combining an audiophile USB interface with an audio re-clocker in perfection! Particularly designed for the demands of high-end consumer audio, the device expands a new sonic universe with increased musicality, clarity, and precision. As such, the MC-3+USB will prove its worth in many audiophile listening rooms around the world.
Additional Features:
Let me first say that The MC-1.2 is outstanding. I currently have an Audio-GD DI-U8 and CI Audio Transient MKII, It clearly bests the Audio-GD and, in my system, narrowly beats out the Transient MKII to my ears (note that I don't have the optional linear power supply for the Transient). The Mutec MC-1.2 isn't cheap at ~$460 street, but it's less than the CI Audio.
It does nothing wrong, and provides a very clean BNC signal to my DACs (I also tried RCA). It can be powered by USB, but it's better to plug it into with a power cord unless you simply cannot do so.
The MC-3+ Smart Clock USB has a street price of about $1030. At the price, it's actually more expensive than the MHDT Labs Atlantis DAC that I'm feeding a BNC signal.
But I must say, this is the first USB interface I've ever used that I immediately thought, "Oh..." That thought can roughly translate to, "oh my gosh I'm actually sure I hear improvement." That lead to some A/B testing between the MC-3+ USB and the stock USB of my DAC. I was able to identify it blindly as my wife switched them every single time.
"Crap," I thought. "I'm about to keep a USB -> S/P-DIF converter that costs more than my DAC." Further, I decided to buy a second MC-3+ Smart Clock USB. One for home, and one for work. Thankfully I overpaid on my taxes all year so I didn't destroy our entire bank account.
Anyway, discuss! Peruse the various other forums that have been commenting on these in more detail. I'll update this thread as others engage and I spend more time with them.
They are highly recommended.
