also, the use of higher sampling rates can improve phase coherency,
sometimes even dramatically.  there have been blind tests conducted (i
forgot the url extacly, sorry), in which 10 pros (using neve capricorn
consoles, earthworks mics, cranesong stc8 compressor) listened to a 16/44.1,
24/96, and 32/192 sampling rate recording of a string quartet.  all 10 were
blown away by the clarity, and separation of 32/192.  subjective, i know,
but still relevant (imho).

i would wonder though, how detrimental SRC would be on such a high quality
file?  i assume that the effects of aliasing/artifacts would scale
logrithmically.. i could be wrong=)

for now, i think i'll stick to 24/48.
