I'd agree with Dwhitt about the AES SixPacs. 50wpc with the standard EL34's, and around 35wpc with somewhat lusher KT-66's. I had Monitor Audio GR60's hooked to them at 90db sensivity, and the SixPacs had absolutely no problem driving them to mid to high 90's db sound pressure. I have been seeing them for under 2k here on Audiogon. You can also get them modified by the factory (Cary) with Jensen Oil caps, balanced inputs (with a switch to toggle between balanced and single-ended), and much better speaker binding posts. Nice amps.
