Allan, Thank you. I think what i am going to do is to pick up a RME Hammerfall HDSP 96/52 and a Apogee Rosetta 8000. This way, i can get multi-channel and mixing capabilities up to 96kz. I understand that the RME DSP 9636 does 192khz which is more desirable, but it will not output 192khz digitally other then spdif (stereo only). Bearcat M.
