I'll get my eyes checked along with my ears though. I figure I'll
evetually be able to tell the diff between 100 and 100,000 Hz!
In Digi's HD 24/192KHz recording, I ASSUME it's using the same analog
outputs as the section that is outputting the 16/44.1.
You can hear the difference in the two. ARE they using different analog?
op amps, right?
