Standmount speakers. I have $5000.

I personally would go with the Dynaudio Special 40’s or the Joseph Audio Pulsars...

The Pulsars sound so so good.  Really sweet and refined to my ears.  I just always love them.  I don’t think that you can go wrong with those Dyn’s though.  I’ve seen them used for $2000.  At that price you could easily resell them if you didn’t like them but I really think you’d like them.

I think counting me, you got 3 recommendations for the Dyn’s and 2 for the Pulsars :-)

Having lived with a volumetrically large living/music space (~ 40% larger than yours) for 25+ years with numerous attempts to use stand mounted speakers (the original Reference 3A DeCapos + 2 subs did the best to create a realistic spl ) I finally stopped chasing my tail as DSP subs were never on my radar, and the only way to dial in a room. Kudos

Since you already have subs with DSP, then definitely check out Emerald Physics open baffle EP-3s (known for killer imaging, but so cool looking the wife just might like them), or their new LSA stand mounts which have gotten some glowing comments
I have owned EP KCIIs for 3+ years. They sound better and better as I up my ancillary game. Cool design, but floor standers

Take a serious look at the JERN14 speakers, in particular the JERN14 EH.  They require a sub or two but they are amazing.  I have owned a lot of speakers and these little cast iron beauties are just incredible.  Do a search and check out the reviews.   Good luck.

@usery boxer v1's were my first, "real speaker." powered them with rogue audio gear. as mentioned, they really do like tubes! 

I just got the B&W 805 D3 and couldn’t be happier....excellent quality speakers.
