who makes auto biasing tube amps w/200 wpc

McIntosh MC2301 300w mono block

The series II and III VTLs are auto biased.

Wolcott P220 monos. (not shure if they are still made?)

Marakanetz

Nope... money is an issue so I'm unable to invest heavily.

Speakers, currently are Silverline Sonata IIIs which I have posted for sale actually. I do have others though. Though, none as good as the IIIs.

They feel like 92 db speakers running at 6 ohms or so, nominally. A BAT vk60 ran them very well to quite remarkable sound levels.

They responnd best to amps with good power supplies. My preff is tubes normally... but The Sonata IIIs don't seem to mind what topology the amp possesses. So long as it's a decent amp or above.

I simply want to get different color speakers and perhaps trade up there too.

So $2K $3K approx. is about the whole budget for amp (s).

Thanks for the Audio Valve note, Bill. Nice amps, but a Wee bit out of the budget. I would actually prefer a Hybrid amp that allows tube rolling in the 200wpc or better area.
