£15k $22k to spend on speakers...but which?

Over the years I've built up a system I like but I've saved the speakers till last because I want to spend enough to get them right. It now saved up and am about to embark on this purchase.

My system is Audio Research Ref 3 & 110, Transparent Super speaker cable and a Melco N1/Chord Hugo (which sounds really good) and Rega RP8 turntable.

I've (initially) narrowed down my speaker selection to:
Wilson Sabrina
B&W 800 D3
Focal Sopra 2
Sonus Faber Olympica 2

I listen to everything from choral and piano through pop to Frank Zappa, jazz, progressive rock and orchestral. I like accurate reflection of the human voice, clarity and good deep dry bass.

Should I look at used Sophia 3? Anything else I should add to my list.

I'd be really pleased to hear people's views as, of course, it is almost impossible in the UK to hear comparative listening tests between these different brands.

Thanks

Matthew
