Very informative, thanks. I avoid 192kHz and record everything at 24bit 48kHz when I'm recording (I would like some hard disk space left, particularly if you're recording 24 tracks at once); 96kHz is only really useful in live applications as you obviously get half the latency which is important if you're flinging audio from one side of the arena to the other.

But with regard to the content within the audio file, uncompressed is obviously superior to compressed. It is particularly apparent on decent speakers, not earbuds.
