Curious, how often do you record at 192? Or even 96? I'm still doing mostly 44.1 though I have a friend who almost exclusively records at 48. For my ears, for rock and pop music 44.1 works fine and dandy.
Most everything I do is 24/44.1.
It's not the availability of higher sample rates in the 192 that give it the edge, it's the over all quality of the converters and analog circuitry.
It's my understanding that a 96 is an 888 with a face lift and a few improvements while the 192 is/was a new design from the ground up.
