Alright, I just put together my first bi-amped rig. An Ampeg SVP-Pro w/ a Crest Audio CA6. Awesome, powerful combination with a tone to die for. My problem? My Back. I just put it all (SVP-Pro, CA6, Furman, tuner, & noise gate) in an ata shockmount. Looks totally awesome and professional, but obviously, very heavy. Would/do any of you have experience with the CA6 and compared it with another power amp of less weight? The CA6 weighs in around 44lbs. I'd like to find a power amp with around the same output (1500w @ 4ohms bridged) and that sounds just as well for about half the weight. Any ideas? I know, I could just separate the rack into two, but it's a little hard to find a 20" deep 2-space rack. That and I like keeping it all in one.
