So I'm thinking about swapping for a power amp/pre set up and was wondering about quality power amps. I've heard of crown and known people who have used it. But I'm wondering if crest is a better brand. It would be something like a crest ca9 vs the crown ce2000 or whatever is around the same wattage. Any other power amps to consider? And I'll be playing the heavy rock with me new nv610 if that matters much. Thanks again TALKBASS!!!
