I’m with you there. Sold my only tube head last year and have 3 SS amps. Two of them are class D, because I’m a sinner.
I'm just popping in on this subject to say that I'm an atheist/agnostic on the subject of SS/tubes - power amp or preamp. I have had examples of both (or all four pre/power amp combos) that I want to take behind the Jr. High and get pregnant. I've been paying my share of a practice space rental because I'm too lazy to go pick up my lead sled, and have been taking the 200W el cheapo Acoustic combo to my stoner/doom/space rock practices recently. Still think it hangs with the best of either style of my other amps, and I have a few of each at this point. I might try my 20W tube amp through my 2x15 Cabinet for bass (seriously, it's surprisingly loud, it should hang with a single combo, at least), and grab another El Cheapo 200W combo to run the synth in stereo if I get to feeling crazily athletic. If I just get semi-athletic, I'll just start running everything through the 300W tube head and the 2X15.
Had practice with the space/doom metal band today. My favorite drummer likes the same line played on distorted bass more than he likes it played on my Moog (and didn't notice it was largely the same (ok, I played it with a weird patch on the synth)). I love him, but I will have my revenge someday.

Really, I should just get better at programming its internal sequencer (or break down and bring a laptop to practice) so I can set it running, grab the bass and satisfy all of both of us at the same time. Ooof, I've been playing too much synth, and when I have been playing bass they've all been strung with flats. The rounds on my Thunderchicken tore my fingers up. Gotta pull that one out more often or re-string it, or stop being a weenie.
But right now I've been listening to a different synth track I laid down this afternoon between work and practice. With stereo outs and one channel going through my trusty English Muff'n (very guitar tube pre) and the other going through a Behringer Bass BDI 21 (SansAmp SS bass pre clone). I keep muting one track or the other, and I couldn't live without either. Most of my recordings have a balance of both of these on each instrument. I have the ability to capture both, and I'd be nuts to pick one. You evangelists on either side are on your own. I'll be sitting on the fence laughing.
And really apropos of nothing, because it's more goth than anything. I finally noticed one of my favorite bass players is rocking a fretless Precision through a GK into a Peavey 2x15 in this ancient vid. Been watching this for something like 30 years and never noticed it. I'm dangerously unobservant, but David J. continually reinforces his status as one of my heroes.
