Olie,
I do alot of PC recording, and I find that while my music (Rock) does not have a huge amount of dynamic range, I still record at 24 Bit, because when you start adding effects (like reverbs and choruses) the tails get jagged. A bigger problem is sample rate conversion, where if you are going to be burning an audio CD, you want your sample rate to divide evenly by 44.1k. So, if you want to start with a higher rate, you're better off starting at 88.2k instead of 96k, because once you downsample, you'll have more noise starting at 96k. I just stay at 44.1k, because my converters only go up to 48k (hey, my Laylas have been flawless for 10 years!)
