Ok, I took some drum takes that I was pretty happy with and dumped them from an MCI JH24 to an HD2 system with 192 I/O's. I opened 2 sessions, one at 192K, one at 96K. I was able to listen and compare to the tape machine. The 196K session was amazing and virtually indistinguishable from the 2". The 96K session was still very good but lacked a little detail, power, and the bottom seemed to tub up a tiny bit. These were subtle differences. The cymbals were most dramatic between the two sessions, the 192K session retaining more of the smoothness of the analog session.
YMMV, hope to see other people's opinions of how they think the new system sounds.
