If you cant go Mcintosh maybe a pair of upgraded Dynaco MKIIS mono amps. I used them with my Klipsch Belles with good results. Now i used Mcintosh MC275s with them. there is a difference but i still love the dynacos tbh i cant bring myself to ever sell them. Def tubes with Klipsch though. Ive tried several solid state amps but even dead flat the horns i cant listen to them for several hours like i can with good tubes.
