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

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.

Running kt88's in a audiovalve Challanger 180 monoblocks will give you 180 watts (auto bias,can run el34,6550 and kt88's).

Some Berning amps are an option. BA-150 is an old amp that puts out about 200 wpc. It was also made by Audionics. This was in the late 70's. These can be had for about 800. New Berning Quadrature is 30K but meets your requirements. Mike
