My main system is A/B system and it is accurate, detailed and has a wonderful sound stage.
I have a tube system in my office with horn speakers and it is warm, detailed and has a wonderful soundstage.
I enjoy both tubes and A/B wether it is SS or Hybrid I like to focus on what they do well and enjoy the music not getting mired down in what they do not do well and listening to the equipment.
The class D gear I have on my deck and had in my office was well just stereo. Filler noise.
