Which Krell for driving subs?

Ulf, I own the Audio Artistry Beethoven Grands and use a Krell FBC200 amp to drive the woofers. The subs sound awesome. Other choices may be either a Plinius SA100MKIII or an Aragon 8008BB, also designed by Dan D of Krell. The subs in your speakers are fairly easy to drive; its the 10" midbass woofers that soak up all of the power. For a seamless match between the bass and midbass, I would go with another Krell amp for the subs.

I must agree with the above posters. I tried both Krell and Bryston before I settled on a QSC M3000. The QSC just sounded better...more slam and more tonally correct. It DID have a fan, but I was able to hide it away in a ventilated cabinet.

The K2 would be an excellent choice.

I agree recommending Crown. Take the Crown K2. It has no fan, is absolutely fantastic for bass amplification. I use it in bridged mode for my Wilson Audio WHOW subwoofer. For Krell you surely pay much more but you may get less.

Be careful when choosing a pro amp like a Crown. I had a Crown for a home demo. It sounded ok, but had very loud internal fans. The amp was intended for use in a nightclub or someplace where it would be located in an equipment rack, where the fan wouldn't be heard. If you put it in a listening room, the fans will be too loud. I don't know iof all Crown amps have this problem, but make sure you ask first. But I think Keithr is on an interesting track. I suspect there are some real high performance bargains to be had in the pro audio world.

Why not just use Crowns or QSCs for the subs and pocket the dough?
