Just to put this in context: most gigging musicians I know have severely damaged hearing, and I suspect most of them can’t hear a thing above 10-12kHz, certainly those who are now in their 40s and older, who’ve been gigging for years beside a drummer without wearing ear protection. This fact doesn’t stop them from making great music that sounds fantastic. For example, I find that most great electric guitar sounds can endure a steep cut above 5kHz without any loss in perceptible quality (and with younger guitarists: with a noticeable improvement!).
Just saying … if the music doesn’t sound so good, perhaps the first place to start looking might not be in the area of Nyquist’s theorem, sampling rate, or D/A converters.
Anyway, back on topic: I use 44.1kHz/24-bit as a default, or 48kHz/24-bit if I know it’s going to video.
