Ok, filter quality. Esben, Fons, on another aspect of
samplerates higher than 48k: Is it possible that what is
audible from an orchestra for example stems in part from
interference or intermodulation of harmonics from above the
audible band? Relevant for the reproduction had the
performance been recorded to discrete channels?
I don't know how to phrase my question better. Gene said Yes
to that if there was "something non-linear in the mixing
process". I didn't understand that though.

Again very true. The main reason why some people can hear a
very very subtle difference between 48 and 96 kHz seems to
be that it's quite difficult to make a 'perfect' filter for
48 kHz, even digitally. There are very few DACs that get
this right (e.g. Apogee, and you pay for it).
