New or used. I have 100DB Von Schweikert speakers and don't need more power. I currently own a Rogue Magnum Tempest integrated which is 42 watts in triode. I like it. Do you think going the SET route is a slam dunk improvement?
Hi R: You do not need that much power (40w) and will not get it out of a set. You could use a 2A3(3watts), 300b (8watts) very easily if your speakers are 100db w/ decent impedance. The lower power may actually be much better!(less is more)
