No gear recs from me. I wouldn't attempt to spend the 6K for you. What I like, you probably wouldn't. Especially since we have two different rooms. I will make the following comments though...
I think a 3K amp driving a 2K pair of speakers is pretty unbalanced system. If it was me, I would do it the other way around.
Also, I would design a system in this order - Speakers, Amp, Source, DAC, Cabling. So far, we know your taste in music, you want to hear every instrument and you do like B&W. So, start listening to other B&W models and other brands that are designed like B&W to zero in on the speaker that sounds best to you. Then find an amp that will properly drive those speakers. This may answer your tube or SS question. Finally select your source and your DAC. Come to us with a short list of actual models so owners of those models can give you meaningful opinions.
Its a journey, treat as such and most importantly enjoy it. You will be on your way to a system that is best for you and not us.
But if you really want to know how I would spend your 6K...
