I'm gettig ready to pull the trigger on high-end preamps and A/D converters for my home system, and I'm trying to decide if 2 channels is sufficient or if I need more. The only utility for more than two channels is for the drum tracking. I already have reasonably good A/D conversion for mutliple tracks (up to 16), and I am wondering if anyone can comment on how much difference it makes if the drums mics are interfaced with good quality preamps (vs. basic preamps, like those on on Digi002 or M-audio Project Mix). I'm not looking for top-of-the line studio quality, but if the pres make a significant difference on the drum tracks, I'll go for a larger premium preamp configuation. Thanks!
