patchmonkey...The RME fireface is a great peice of kit....I was put onto RME by classical recordists (Linn HiFi, Finespice Mastering) they swore by the converters for location recordings...@88.2Khz/24bit I can run 13 tracks (or more) in record, with the same amount playing back @ 128 buffer settings on a dual G5 with no annomolies....I recently clocked it to a Big Ben, 'cause I was using an ISA 428 (with AD card) via ADAT into Fireface....ROCK SOLID for hours....great sound....honestly you'd have to spend a lot more money on converters to get better...
