Why do Tube Amps sound more romantic v SS amps

Good tube amps on a transparent system are incredible. You can hear the room, and that’s really all I can ask for.

That glow in the dark factor turns into a smirk whenever the lights are dim and you’re in the middle of an audiogasm. 😄😎

Grab a tube when it's running full tilt and see how "romantic" that feels. 

Tubes have been romanticized for some reason, using terms like "warm" (any coincidence a tube is warm when it's operating?) and it continues to this day.

In the seventies, I started out with tube amps & preamps.  Then I kept the tube  preamp, but went to a SS amp. Then I went all Hafler preamps and amps. Then I went back to all tube, until last year. For the first time, I went Class AB, SS integrated and have been very happy. However, I have a lead on some PS Audio BHK 300 mono blocks and they are a tube SS hybrid. 

Not always. Right SS match is hard to beat with  tubes. I do have old Mcintosh MC-2255 with C-33 and I think will be very hard to find tube match with sweeter and romantic sound how you said.
