I talked to Dave S. on the phone asking specifically about the usb as I'm used to using a Lavry and EMU1212M via coax or toslink to pass native 24/96 material as well as 44kHz material upsampled in software.
He stated that it would be okay to pass 24/96 over Toslink or Coax as their usb protocol doesn't do anything above 44.
So, here's the problem. EMU cards can't switch on the fly. What I used to do was set the system at 96kHz and have J. River Media Center do re-sampling of anything less than 96 (hi-rez downloads and vinyl are 24/96)
I can set J. River to use "source sample rate" which will allow the NOVA to upsample 44kHz content, but what is going to happen when the NOVA gets native 96kHz material.....?
How about if I resume my old setup and use a software resampler to send the NOVA 96kHz....sorry for the ignorance I have just ever owned an upsampler before.

The Nova's DAC is 24/96. There was initially some confusion because the Sabre DAC we use is capable
of 24/192 but only when using a receiving chip for the SPDIF inputs. But we found out that if you go directly in to the Sabre DAC like we do and not use a receiving chip it sounds better. However that means it isn't capable of 24/192. One thing to keep in mind in the 24/96 vs. 24/192 discussions. You can only hear a positive difference between the two when using audio content that is actually streaming at 24/192; and since less than 1/10th of 1% of all recorded music is at that resolution we decided to utilize the direct 24/96 circuit for better sound on a wider variety of available recordings. If you are upsampling a redbook cd to 24/96 or 24/192 there is virtually no difference on most DACs that are capable of both resolutions. The general quality of the DAC is much more important. I know this must sound confusing but there is a logical reason why we chose 24/96 instead of playing the numbers game.
