Louis1,
I have owned many famous SS amps, including BAT VK-600SE and Clayton M-100, and have heard many others, including Clayton M-300 and Pass XA-160's.
That said, while I agree with Tvad that I don't quite understand the need for that much power, I think the Clayton M-300's or the Pass XA-160's will fit in your price range used, and both will EASILY drive your speakers.
The BAT VK-600SE was very nice, but the Clayton and Pass are better, IMHO.
If you crave the tube sound, you will find a pair of VTL MB 450 series 1 or 2 will fit your price range, and also EASILY drive your speakers.
Happy hunting,
John
