Hi, I have been doing a search for "high-end" converters. I came across the Mytek Stereo 96 AD DA series. Anyone else using them? I have already given up from the Apogee Rosetta 200, Aurora 8 and the 192 I/O. Also, do you guys use mixed brands for the a/d d/a? For example, use a more expensive a/d like Lavry Black and a simpler D/a from Apogee, Mytek?
