Anyone has a reference system where amplification is SS ?

OP writes:

(A) There are preferences and subjective elements and there is also objectivity

(B) Why would you go with those SSs instead of tubes, practical considerations aside ? They would never give you the midrange that those valve amplifiers would?

I'm not sure whats being argued here in (A) with the reference to objectivity. The fallacious argument from authority statement in (B) appears to be implying that this completely subjective statement is objective. But perhaps I'm misinterpreting.

Anyway, the term reference in a hi fi context is meaningless. It would appear from the post above that the OP sees "reference" as the best available. If that is the case then there are legions of solid state amplifiers which qualify including Pass XS, MBL, Constellation etc, etc. The "why would anyone go with those SSs instead of tubes? conjures up the old Monty Python "what have the Romans ever done for us?" sketch - power output, dynamic range, S/N level, damping factor - and consistency where the sound doesn't change when you replace the output devices, are a few things that come to mind.

@OP "Personally, I will never have a reference system but will always have a good sound with tube equipment and analogue source wherever possible. The core of any music is in the midrange, and if you don't get it right more or less - forget about the rest. Choice of tubes is very important too, the difference can be dramatic, as everyone knows."

That's a rather different argument to the one you started the post with?

@OP If "reference sound" is sought then tube rolling is a disadvantage. How can you have a reference if the sound changes everytime the active devices are changed?

@invalid - I haven't argued that SS devices are transparent. The point is that, assuming that the manufacturer is strict about tolerances, SS amplifiers will sound the way they were designed to sound. Tube equipment will sound different depending on which tubes are installed.
