Raul, I'm an electronics technician, that's how I earned a living. There was a time when I lived by specifications, and SS was always the best.
When my highly rated SS preamp bit the dust, I decided to try tubes. A dealer sent me a a CJ tube loaner, it was a PV10. This preamp had "apparent" distortion, there was no mistake about it, but the music sounded better.
I invited an audiophile friend over to evaluate who hears better than me. He immediately noted that although there was both noise and distortion, the music came through all of that, and it sounded better "musically".
Some people like the "sound" of things while others distinguish how close whatever it is to live music; it's possible that the sound they like is not the closest to live music.
I believe what I say is "true", while you believe what you say is true. In the end, it's not about the truth, but what you prefer.
