This depends on what one's idea of tube amp sound is. For most people tube sound is typified by overly warm lush mids, softened highs, weakened dynamics, and loose sluggish bass. Basically, your everyday 12AX7/6SN7/EL34 sound, best exemplified by Cary. This to me is a bastardization of tube sound, it's crap.
Good tube sound is nothing like that. It is every bit as clean & fast as the best solidstate, but adds much better tonality, soundstaging, and realism. There's no colourations nor excessive warmth, no softening of treble & dynamics, and the bass remains deep, tight, and impactful. This is the sound of a good 45-based amp.
Is the midrange warm? Depends on what one puts in front of it and after it. With an RCA grey glass VT-231, yes, it will be, with an ECC99 or 26 there's only a trace of warmth. Stick a run of the mill output transformer on it and again it will sound rather warm & sluggish, with a good amorphous or cobalt core transformer and once again you're back to the sound of the tube, or rather, whatever tube(s) is in front of the 45.
This assumes of course that the power supply for both the filaments and B+ is up to the task along with the rest of the parts. Put a single electrolytic capacitor in the power supply, even if it's a Blackgate and you will hear it, and it won't be good. You're looking at levels of refinement & resolution which are beyond anything which is commercially available, with the exception of something like a Kondo.
