I doubt that you couldn't physically tell a different between a typical solid state amp, and a tube amp. For one thing, a tube amp likely sounds warmer. But such a difference probably doesn't matter to you, and hence it's effectively indistinguishable. Many people, including musicians or music lovers, are like that. But that doesn't mean they do not physically hear a difference.

Listening itself is complicated too; I don't know if I could hear distortions (unless it's obscenely obvious). Most of the time, I can only notice their abscence. And I have seen this happen with my friends too. In one case, a guy said his system doesn't have any distortion, until he listened to mine. So now, when I feel the music is too loud or irritating, then I know it's distortions (which are a dynamic function of power line conditions and how long i've been listening) that are kicking in. That's why I think it's very difficult to capture distortions/fidelity with a simple set of numbers.

As to compromising and unwanted noise, my amp has the loudest 60hz hum that any I've known, but it is much better than many others, solid state or tube. This is due to its design (direct heated, directly coupled single-ended triode with a very simple power supply circuit). The designer could reduce the hum and other means such as a different design. But I doubt they would have resulted in what i'm hearing.
