Gudiocorona, Ill try to describe my preference . I like a neutral but not a thin sound, I like bass that is deep but fast. I would say its a mix of SS speed with the fullness of tubes. I have no special prefs. for either technology. I used to own a Spectron MIIISE and a VTL TL7.5 with Wilson WP7. Although I got to much noise from this pre/amp combo. I think there might be some trouble with AC noise but not sure.
