This could be just what I've been looking for. One question though, can anyone confirm if 24/192 is available via the optical output? I've seen quite a few products that offer 24/192 via coax but only 24/96 through optical.
from a table I found online:
2.8224 Mbit/s 44.1 kHz sampling rate, CD, DAT
3.0720 Mbit/s 48 kHz sampling rate, DAT
2.0480 Mbit/s 32 kHz sampling rate, for satellite purposes
those are for the 'old' sample rates.
if we take 3mhz as the 48k rate (close enough) and multiply it by 4 for 192 we get 12mhz.
my guess is that the 16mhz parts may work and the 25mhz parts really *should* work ok, for toslink.
realize you need 'good parts' on both sides to make it work.
