THANKS to EVERYONE for your thoughtful and amazing replies. So glad I finally asked for feedback from the experienced group of audiophiles and engineering minds here on Audiogon. Some very cool examples shared by all of you!
Still holding on to separates for now -
I really dont want to give up my separates, monoblocks, and other class A SS stereo amps, UNTIL there is something that moves the needle for me to actually get myself to part with my existing amps. It will be hard to do, and considering it.
Quality Transformers -
Most inclined to follow-up on the integrated tube amplifiers with the best iron, quality transformers as many have commented here too - this is where the best sound begins.
i.e. Watch the video of the guy at AudioNote with headphones on that does not thing but listen to transformers at the factory to pass/fail them for installs in amps.
Budget -
While I’m NOT going to spend $20k on an MEISHU Tonmeister [yes, amazing, very nice] I’ve heard one about 5 times at a local AN dealer. However, maybe I could find a very nice [proven reputation] tube integrated for $8k-$10k thats "good enough" is my current thinking. Likely could be a tube integrated, hybrid tube integrated, but tubes for sure in the preamp section [at least] or full tube integrated amplifier is still on the radar. I think I'm still a tube amp guy, hard to shake it :)
