I disagree wholeheartedly, with the caveat that one man's insignificant is another man's significant, and not having the experience with 70s and 80s tubed gear I imagine it's possible there was a more significant sonic difference between SS and tubed equipment during those decades. If that's the case, then it stands to reason one could consider the differences less today based on the earlier sound as a reference.

the issue of tubes vs solid states for the current generation of tube preamps and amps, exluding set amps is a non issue.
the differnces between the sound of ss and tubes, especially using "dynamic" speakers is very small and insignificant.
However, I have heard substantial differences between tubed and solid state preamps and amps on my dynamic loudspeakers. All the equipment was manufactured after 2000.
