96kHz is not bad, 192kHZ IS bad. 96 pushes side effects of filters in
the A/D/A chain beyond out hearing. However, it's suspected that 192 is
not so good as there isn't sufficient time between samples to allow
components (e.g. caps) to function correctly. I think I've said this
before but read Dan Lavry's paper on the subject at

http://lavryengineering.com/documents/Sampling_Theory.pdf

Yes, Dan Lavry does makeand sell ADCs but this subject has been
discussed to death on a number of audio lists and forums frequented by
many eminent engineers. It is the concensus that 96kHZ is a Good Thing
(tm).
