Re: CD player
Deniz Baskent suggests a high-end CD player by Tascam, which she and her colleagues found to be relatively distortion free. Normally, we play things via Edirol external sound card in the lab..but at the moment for this experiment it seems like we'll need a free-standing audio player of some sort.
I'll take all your input into account -- many thanks, all!

Another idea would be to use a portable audio player that can play
lossless audio formats like WAV or FLAC.
For example the SanDisk Sansa Fuze can play WAV and FLAC
(http://en.wikipedia.org/wiki/Sansa_Fuze). Or use an iPod together
with http://en.wikipedia.org/wiki/Rockbox :)
