Tube sound is not about warmth. It's about correct presentation.

Modern tube amps and hybrids are the the my preference. 

Disagreed.

Also assuming tubes provide “warmth” then that’s a problem because warmth might be nice but it’s definitely not “correct”.

So the logic of the assertion proposed is flawed to start with and that kind of puts a damper on things right out of the gate.

I started with tubes, then went to SS, went back to tubes and then a couple of years ago I bought my first integrated amp.  The Hegel H390 sounds pretty darn good to me. Maybe in a couple more years I’ll go back tube separates.  Or maybe Hybrid amps like the PS Audio BHK 300’s that use a couple of 6822’s in each mono block to give the user more of a tube sound.

Love that simplicity Curious Jim.

Hybrid amps are SS amps.
