Why is solid state more popular when tubes are better?

I find my tiny flea power class D amps to have some of the subjective character of SET amps (to some degree, of course, but more so than many "traditional" class A or class AB solid state)

They have been ON for the last 10 years, 24/7, just like the rest of the system. The only device I turn off at night is my DAC, because its massive discrete output stage gets quite warm and it also uses more electricity (!) than my amps (really, I'm not making this up).

I've become addicted to the convenience and absence of fuss - the system is ON, all the time, I just need to press "play" and tadaa! music. Even tho I'm constantly trying to improve (as many audiophiles do), I'm extremely reluctant to change the amps. 

I've recently added some Duelund speaker cable and it added the slight warmth / bloom / liquidity that I was missing. I believe one could be fooled into thinking the system uses tube amps, in a blind test.

I’m also wondering if music genres would influence the debate.  It seems like classical music lovers gravitate more towards tubes.  I’ve had both and made the switch to SS a long time ago and never regretted it (although, I would consider a tube pre under the right circumstances).  I listen to rock, jazz, and blues and can’t imagine tubes being able to capture leading edge transients the way SS does.

Agree Ralph from Atmasphere, Solid state are almost free of maintenance why they prefer them, Yes Tubes sound different than solid state. On summer I used solid state, winter tubes. They are both excellent if you know how to match them.

The thought that Genres of Music should influence whether to you use tubes or not is absurd. All genres of music except awful rap contains a wide diversity of musical instrument representation. Less so or more so, it’s all there.

OP so how did your comparison of the tube monos vs SS go?! Any thoughts?
