Recommend speakers for Hegel H190


What speakers under $5000 would you recommend for Hegel H190?

Used in a room that is 6x8 meters, high ceiling. Currently have B&W 683 S2 and like them but would like to improve.

Thanks for the advise.

I think the LSA 20 Statements would provide significant improvements in every aspect over your B&Ws yet retain a fairly similar overall sonic signature with more refinement.  Bass goes down to 25Hz, which in itself should be a revelation.  They’re being discounted here for $4500/pr by the manufacturer and include a nice pair of speaker cables in the deal, and they offer a 30-day trial period that is particular nice now.  Best of luck in your search. 
How about the Splendor LS3/5a or Harbeths line? With the extra money you can add a used sub or two. Hegel line is a little sterile sounding but with great detail and good sound stage. These speaker lines will add some warmth. You get the best of both worlds. 
Picked up a pair of used Joseph Audio Pulsars last fall after many many years of changing nothing but evolving sources. Reignited the bug for more. Found an Atma-Sphere pre that is now a keeper. In process of auditioning amps, am listening to a Hegel H20 as I type this and enjoying it very much. Very engaging, dynamic with great soundstaging, speakers truly disappearing. No doubt the Atma-Sphere deserves some of the credit, but the Hegel and Pulsars seem to play rather well together. Think I gave $3.6Kish for them. Prior owner upgraded to the latest version. They don't seem to pop up often, but if you do catch wind of some being available they are certainly worth consideration. Believe they are $7k new?    
I use a pair of Sonas Faber Concerto and REL with mine, it works fine for my needs.
If I upgraded speakers I would be looking for either a better SF of go to electrostatic speakers. However, going down that rabbit hole can get expensive. Mine is fed with Blue Node 2i , Apple TV digital inputs. For single artist recordings I love it, for group performances or classical recordings it’s more just a grin, you’ll need to spend some money to reproduce that.

Good luck.
