For many years you could find ProAc and Audio Research gear mated at audio shows.
I heard D80s powered by a pair of VTM200s at Alexis Park 5 years ago and thought it sounded pretty good, but not as expansive as I had hoped. It could just have been the crappy "show conditions" though.
In the past I owned Tablette 50 Sigs, 1SCs and 2.5s running off Blue Circle, BAT and Pass Labs preamps and amps. I found some personal magic with some of those combos.
What seemed to work for me was a tube or SS non-OS DAC into a tube preamp feeding a solid state amp. Hopefully, this will give you an idea of my sonic preference and how it relates to yours.
