I've always wondered how 2 watts would sound on my speakers. I've wanted to try 2A3 or 45 amps. The I-Bens are the same efficency as yours, so tell me, how does it work?
What kind of music do you listen to and how loud?
Does it ever run out of steam under normal listening conditions?
PS. You have got to get into LP's, that's where our type of systems leave others in the mud. Spin a couple of platters and you'll be hooked for life.
