JohnK, excellent post once again.

This really brings up the question as to whether 129khz recordings sound any better. I have found, however, that DVD's at 96/24 sound better than CD's at 44/16, but that may jsut be because the master recordings were better.

Patricia Barber's Modern Cool CD is only in 44/16 but its master tapes were 24bit, i assume.

So maybe one day there will be a digital format offering 256/32 but no one will hear the difference
