Well designed solid state gear can indeed have "warmth", and often more accuracy...If something is on a recording I don't want it masked by euphonic distortion or anything else. I've heard amazing low powered "SE" tube amps that sound amazingly accurate (to a wattage limited point) and solid stuff that is lifeless...so It's up to the designer how things are voiced and the listener to how it all tastes, so to speak. Warmth for me is lack of harshness. Period.
