Tubegroover is right on every count. As far as which is better, I prefer tubes. I cannot say that solid state couldn't make me or another person happy. But, I do know there is a certain rightness to me with tubes that doesn't come along very often with solid state. Some people accept NO substitute for tubes. The best analogy along those lines I have heard a person put it is tubes are like having a dog. Yeah, they mess on the floor, need to be walked, fed, etc. But, they are a real, living thing. Solid state is like a stuffed dog. No maintenance, but nothing else(feedback, reciprocation, realness, etc.) either.
