"What I find is that warmth is more often the thing I hear rather than bright and harsh, the latter being a common hallmark of solid state, hence the existence of this thread :)"
The other possibility is neither warm nor bright and harsh. I'd call that more "neutral".
Some SS amps are more neutral or less bright than others. Same true with tube amps. I don't think either wins categorically anymore these days in general though perhaps that used to be true to a greater extent. The technology on the other side of the fence from tubes is anything but stagnant.
Also neutral may be considered better technically but not all like the same sound best, even neutral. Just like most people but not all like vanilla ice cream and some prefer others with more distinct flavor.
When it comes to sound, I am in the camp that thinks neutral is always better, however it is achieved.
