I too get tired of small tube amps every now and then. AAMOF the only tube amps I love are Transcendent OTL's. Nothing like a bunch of high priced tubes glowing. For decent sized SS power (120wpc) and low cost, I bought a used ATI amp. Odyssey makes a good one too.
I wish I could afford Nelson Pass' SS amps and Roger Modjeski's tube units. But then, how could I build a never ending stream of speakers?
