Hi, Ellis,
My guess is that the DAT machine re-linearizes the audio before sending
it out the SPDIF spigot. I think DAT machines also throw in the
de-emphasis, but the ES-601 F1 system does not do that on its digital
output but does on its analog output (I think), but that is an earlier
design.
Cheers,
Richard
