Even though the Rosetta 800 can go up to 96 k you can still use it at 48 or 44.1...Get the rosetta and forget the adat bridge...I own the Ai3 and I also own the Apogee Trak2, so if you're really willing to spend the money on converters alone (rosetta 800 8 ch. of a/d d/a) the apogee stuff is really good...Though I've heard decent things about the RME so you should check that out also...
