There is great solid state and great tubes. I could live happily with Pass, Gryphon, D'Agostino, ARC, VAC, Triode, Viva, Audio Note and many others. There are things tube amps do (like tonality) which SS amps fall a little short. Then there are things solid state amps do (bass, dynamics, etc.) that tube amps fall a little short.
The key is to find the right amp regardless of solid state or tube for the speakers, the music, the room and the budget.
So far, pure Class D is the only amp topology I don't find appealing. Class D is good for cars and subwoofers. It's like junk food of power. Lots of it for cheap, but not necessarily good for you and way over rated. Class D power ratings are so full of crap in many cases. Take 1/10 of the power rating and you will get real world power. No, not in all cases, but in many cases. That has been my experience at least.
I would take a JOB225 A/B amp over any class D amp on the market today - including Moola Moola.
