RE: Hey Mark I have anecdotal data from listening

Hi Mark & theob,
Good to hear from guys who have given this a try.

I agree that 24/48 is the sweet spot both from my own listening and I think this is backed up theoretically as well. With 24-bits, there's absolutely no way any of our current technology can reach this level of dynamic range (not like any music would ever need anything even close to this!), and 48kHz gives a good transition band above 20kHz audible frequency for the DAC to implement a reasonable filter.

As I said in previous posts, I believe if the CD standard were 20-bits (2 bytes + a nibble :-) / 50kHz, there would be little for anyone to complain about with any justification.

BTW: As for 192kHz, there's very few actual recordings out there of this quality IMO. In fact, I don't even know which microphones record sounds flat to 30kHz, much less represent the full spectrum of the performance that such a high resolution format would afford (we're not talking bat detectors here :-). Other than specialty audio like 2L, most of the other 192 stuff looks like DSD conversions or upsamples to me in the audio editor.
