All things being equal (which they never are), I would go with a high efficiency floor stander. Consider one with a widebander for a midrange and minimum to no crossover and you'll find it come alive early on with the ability to flesh things out and do it all with great coherence.
I'm not even going to begin recommending a brand as I believe when it comes to speakers, you have to personally audition them. So take a good, hard look at all the high end dealers in your area or, if not too far a distance, take the time and make the trip to listen to one. For 5 grand, I would. If there is a speaker that tickles your fancy and not within a reasonable distance from you, ask the maker if there is anyone in your area that would let you audition it. That's how I bought my Legacy Classics many years ago. I've since moved on and tried a couple of speakers, hearing unheard, and regretted it. My last speaker was done the right way, by listening to it.
All the best,
Nonoise
