"The main thing that distinguishes a tube amp from its SS equivalent is the inefficiency of the tube amp."

But, there is another distinguishing 'thing.'

If a modern - or modernised - valve amp has maximised its storage, which they can do to an extent which SS amps would have real difficulty getting even close to, then that amplifier can IME outdo most SS amps, even in the bass.

Large storage PSU's consistently sound better.

I used to own a rebuilt and rethought STAX DA80 pure class-A SS amp, new and higher uf PSU caps, SR diodes, and with its slightly cloudy OEM driver stage replaced. 45WPC into 8 ohms and very nice.

Compared with two rebuilt max-storage LEAK St20s with a teeny bit (1 to 2 dbw) less total power 20 watts plus maybe 6? watts. Passive bi-amped.

Guess what all experienced listeners preferred? The passive bi-amped set-up.

Guess which technology was happiest playing real loud?
