Well... Maybe.

I've read that tube amps are "better" because when they're over driven, they don't clip as "hard" as solid state amps. After some thought, I've concluded that it's not an inherent characteristic of vacuum tubes that causes this: the "soft" clipping is due to the inherently limited frequency response of the output transformer. Clipping introduces all sorts of extra frequencies required to create the square wave part of, say, a clipped sine wave. A transformer cannot pass the required high frequency components required to create the sharp corners. The output transformer acts as a band-pass filter: it can't pass extremely low frequencies nor can it pass extremely high ones. Solid state amps have no output transformer and so pass whatever frequencies the device can handle and they can likely go much higher that 20 kHz. Thus, we see sharp, square corners on clipped output form solid state amps that we will never see from vacuum tube amps all because of the output transformer.

  This is true. Tube amps and vinyl do sound better. Also, Tube guitar 
amplifiers sound better, and a Hammond B3 sounds better than an XK-3 (but it's 
hundreds of pounds heavier).

Roger.  From what I understand, vinyl records played through a tube
amplifier sound better (technical term).
