there does seem to be more that you can do with the encoder, as the itms
stuff seems to be better quaility at 128kbits than self ripped in
itunes.

i found that at 128 kbits i could tell at 160 most music sounded a bit
dead, and at 192 i struggle to tell any differnce between the cd and the
ACC i'll see if i have any duplicated in itunes at differnt bit rates
prefubly one that is a itunes store one and have a listen on the main
system.
