I'm currently using a crown ce2000 amp in my rack. this amp has been a real workhorse. it's loud and ive never had a problem with it. lately i've sold a few things on ebay and played more gigs than usual, so there's a little bit of cash in the kitty to buy some new bass gear. although i like my amp i'm starting to feel that maby i could do better. i'm considering buying a new poweramp. i kind of like the buzz i'm hearing about the crest ca-9, but i have no idea how one would stack up to my current poweramp. anyone out there have experience with my amp vs. other quality amps? i'm also considering maby a crown macro,but i just don't know. any other amp recommendations? i'd probably buy used something less than $1000. i play a 4 string and slap alot. and we usually play loud. so lots of clean power (at least 1500-2000 watts) is paramount.
