Tube amps are not best pairing. The 3.7 dip to 3 and 4 ohms, I've heard the 2.4 with Primaluna100 tubes and did not sound as good compare with a ML331. 3.7 is awesome speaker and would sound good with any amp, you just want to feed it the wattage it needs.
Anybody using tube amps to drive Thiel CS 3.7's ?
I currently use a Classe Delta 2200 and a Conrad-Johnson CT5 preamp. I'm considering a jump to a tube amp. 80-100 kohm input impedance would be nice and I'd prefer only input from those who've heard Thiels driven with tubes...Thiels are hungry for High quality power. I have a moderate sized room (21 wide by 15 long). Let me hear your advice.
