I stayed solid state. C55 with MC452. I like the app versatility. I had the c53 and swapped it for the 55. 456/462 has plenty of ass to drive about anything.
I ran B&W 803D speakers for a while. Loved the setup. But now the amp and pre are in my man cave powering MCXR100’s which I had in my living room. Too much speaker for the room. They do well in the cave. But honestly I like the B&W voicing so much. I got a set of 805D4 Signatures for in there driven by a MA8900 with a DA2 board. They are delightful.
That’s my only integrated. Small space. It’s great. Big space I have the separates and considered the MA12000 but just did not want to deal with my perceived hassle of Tubes etc.
not sure if my thoughts help, but in the caliber of what you are considering, my humble opinion is you can’t go wrong. It’s all about the space you are trying to fill.
And of course your subjective feelings.
