I've heard a pair of Classe Ca-200 bridged, and was not impressed. I thought they lost a lot of the music in the bridged mode. If you're talking vertically biamping, disregard the previous comment. Have you tried one CA-300? I would rather go with one CA-400 or a pair of the older 700 wpc monoblocks, than bridge a pair of 300's. That, of course is just my $.02
