I found a pair of mint Carver Amazings

try a Carver sunfire amplifier or maybe a pair of them

I listened to a pair of these Friday afternoon. They were powered by the biggest Bryston stereo amp and a current model Levinson amp rated at 200/400 wpc. Neither of these amps could get these speakers to open up. I was thoroughly unimpressed. To be fair though, i did notice that one of the ribbon tweeters was moving in unison with low frequency input, so my guess is that something was very wrong with at least one of these speakers. Sean

Try a big Plinius amp, the Carver's need lots of power with no amp strain as they get bright very quickly. Old Krells (not the KAV line) would work fine also. Aragon and McCormick comes to mind also>
