In my experience the nyquist theorem holds true for sound quality. 44.1 is enough to cover our hearing. If you are really anal and want to hide dither above 20kHz then 48kHz sample rate is fine for that.
Something i did fooled me once when i was messing around. Go into a destructive audio editor like Soundforge or whatever wav editor you have. Generate a high pitch sine wave in 44.1kHz and look at the visual representation it gives. It will *look* REALLY jacked up like it is missing information. But then convert that sine wave you just generated to 96kHz or something higher and it now looks like a sine wave. Magic the nyquist theorem works.
