EL34 Lovers?

Audio Electronic Supplies(AES)Super Amp MkII, designed and manufactured by Cary Audio in NC, USA.

Fast, airy, dynamic, great frequency extension, with good bass. It sounds like a cross between SS and tubes.

I am using it with a full compliment of EH tubes for the driver, input, and output tubes. These tubes take a long time to break in. They are harsh for 100s of hours before they settle in, but they have great extension and tonal pitch.

I've heard that KT88 can sound quite good and I have yet to try them. The Super Amp 2 is so versatile it can use 6 different output tubes and also be configured in triode as well. This amp looks like Cary discontinued Rocket88 that used KT88 tubes so it makes me want to try it sometime.
