I can add some thoughts here.
I owned a Devialet 220 fully upgraded. I agree with Elberoth - Focal (Sopra 3) is not a good match (way too analytical and bright) but Dynaudio (Contour 60s) and Sonus Faber (Amatis) are a decent match. I tried all those combinations. My preference was actually the Magico S3 mk2s (took me a while to get used to non-ported bass), which is almost counterintuitive.
Have you purchased the Devialet? I think it is extremely good value for money. But my advice (having been there), and assuming you can up your budget, is try some other amps before you buy. It is more expensive, and I am biased as I upgraded my Devialet to this, but the Gryphon Diablo 300 (or other similar integrateds, although I personally haven’t come across anything as good as the Diablo 300 at its price) is the better option. You will of course need a DAC (people on this forum rave about the Diablo DAC module) and maybe streamer (not sure if you are all digital) on top of that. If money is an issue but it is a 6-12 month issue, my advice would be wait, save, and buy the better gear.
