Krell man, I really didnt like the sound of the Nuforce. Is Spectron more "tubey"? Rleff, good suggestion, but I think I'm stuck with getting her an ss amp. Furthermore, my SP Tech speakers really need a lot of power and the MA-2 certainly does it adequately, but I dont think half the tube power would do it. 150+ watts of solid state power, closer to 300 if I get any of the amps I'm thinking about, should be better.
