Arthur, sounds like your speakers will not like a SET or low powered tube amp. I would recommend that you stick with a push/pull design that uses pentode tubes (EL34's, 6550's, KT88's, or KT 90's for the most part) and puts out at least 40 to 50 WPC. The ASL integrated could be a great and ecconomical place to start. FWIW i find that the same tube in different amps will sound different(and a different brand of the same type of tube will sound different in the same amp) so sound wise its not just about EL34's or KT88's. It all in the application. good luck......
