So I just bought a Hegel H390 and

Okay you erred by buying the INT ahead of the speakers but you
made a great choice so you're not boxed in.

The most musical sounding Speaker we heard at a recent event was the
Sonus Faber Electra Amator 3. Fits your price range. 
In a smaller room a 3 way might not work. That speaker is one of the sweetest sounding I've ever heard. Quit reading now and buy it!

In your 15 x 15 room consider headphones or at maybe some
LS 3/5s in near field configuration. Or just save your money.

My friend has the H390 paired with the new Dynaudio Heritage and its absolutely sublime. A few other people have this exact combination and their feedback tends to agree.

I am not sure if its the amp or speakers, but it’s slightly, and I mean slightly, to the warm side of neutral. The presentation is a bit laid back (but not dull) and completely natural and coherent. You can listen to a lot of music on this combination without fatigue.

Before getting the Heritage we auditioned the almost twice as expensive Confidence 20 with Moon amplification. A totally different sound, more hi-fi, and IMO not very good at all. Maybe it was the Moon gear and not the Confidence 20, but I did not like it and thought it way overpriced.

But some Dynaudio fans have been saying they like the new Heritage better than the Confidence, so it could be Dynaudio have voiced this speaker for certain tastes.

i would agree the h390-590 are voiced slightly on the warm side of neutral (but without tube-like midrange ’bloom’, just smoothness and luscious tonality), and the treble is definitely on the restrained side but still with excellent detail and vivid spatial representation, heard through a deep dark background (similar sound profile as pass and ayre, but hegel does bass better than ayre imo) ... thus folks with highly resolving systems seeking a more natural (rather than a ’super hi fi’) presentation love the hegels

Thanks jj,

This is why I was asking about speakers.  I don’t want to add a warm amp to a warm speaker.  So the amp should be here today and then I’m hopefully going to listen to Dynaudio, Focal and?

Jealous of that amp!
I've heard Dyns are a great match for Hegel. And if you've never had dyns you should give 'em a day in court!
