I've been thinking of using my Gallien Krueger 700RB and SansAmp Bass Driver unit as preamps into something like a Crown K1 ..... I've been reading that Mackie's m1400i is really good for the money, but I don't know if I'd be losing a ton of sound quality potential if I buy a more budget power amp. I like a pounding, very articulated, mean bass tone. I think I'm getting it already with my current set-up, but I think I'm pushing my GK pretty hard and would like to free-up some head room. Does anyone know much about poweramps with super high damping factor? Crown claims to have the highest damping factor of any power amp. Their K1 and K2 has something like a >3000 damping factor. What will a high a damping factor translate to in sound quality? I assume that it increases the level of punchiness and clarity. To anyone who knows, please elaborate.
