Are tubes psychological?

Is it any surprise that people describe tube components as sounding "warm" considering many tubes produce tactile heat? Whoever started that silliness didn't work too hard to come up with it.

I rarely listen with my Luxman SS any more. The Mctubes just sound nice. Whereas the Luxman somehow seems sterile.

My all-tranny Mytek server+phono stage generates a good two-thirds the heat as my eight tube integrated PrimaLuna. Plus, there's no on/off switch like the PL's got. When I switch my components off for the night, the Primaluna cools to room temp. Meantime, the Mytek, even on Stand By, still stays warm and sucks from the grid.

Tubes gives a more “natural “analoge” sound . Very detailed,more 3D: you “feel” the music more than with a transitoramp: is more digital :: ampathizing with the music is less by transistor 

First of all tubes sound amazing compared to solid state. Second, tubes are just really cool. I enjoy watching lightning in a bottle help me hear music.
