So I just bought a Hegel H390 and

@jjss gave a good framework.
My two cents is that asking "what matches to the hegel?" is the wrong question.  Any really good amp ought to work well with a wide variety of speakers.  what you really need to ask is "what speakers do I like?"; what speakers can drive my room?" and "what speakers are appropriate for my musical taste?" etc.
A really great amp ought to be a chameleon these days. Mine is.

With the limited number stores around me, hearing most of the speakers discussed will be really hard to do, so I’m thinking I’ll get a pair of LS-50 Meta’s, as several have suggested and go from there.  Everything I’ve heard and read says even if I don’t like them, they should be pretty easy to resell.
Again,  thank you all for your suggestions.

In your 15X15 room a closed enclosure speaker might help to control bass better than a ported type, I have a room very similar in size and Magico ( old V3) made it for me, that after many trial and error…

Amazing amp!!
congrats. Will deliver years of musical bliss. 
   Looked at Hegel years ago, I was turned off by the “stuffing” of so much in the stereo amps, caps, wiring, VA torroid , etc. 

   Hegel is great stuff.

plenty of power for hundreds of great speakers. 
   Would take the suggestions on Dynaudio, they are amazing. Only reason I didn’t go Dynaudio is it was only a few hundred more than what I bought. 
  Enjoy, you made a great mp choice for sure!!

 Report back after your ears are accustomed to her.  

Hello,
The Hegel products have a really good damping factor. If a typical amp would have say 1000 damping factor I believe this amp has 4000. It’s amazing how even their smaller amps like the H95 can drive Maggie’s. This H390 is second from the top so it can do it with ease.
