The thing is, a well designed tube amp can be as transparent and neutral as a good solid state amp. The problem here though is the virtue equation, the tube amp will be more expensive, consume far more power and the sound degrades over the life of the tubes. The virtue equation doesn't matter much though because those that typically get into tube amps do not want a neutral, transparent sound and most high end tube amps have intentional colourisation for that audience.
Likewise, a solid state amplifier can be made to sound the same as any tube amplifier. However in this case, people who buy solid state amps are not after a tube sound.
I remember the Carver challenge that he could make a cheap solid state amp to sound exactly the same as any high end amp, tube or solid state. The challenge was taken up by both Stereophile and The Audio Critic and both lost.
