So to bring the post and original question to some closure... never did get to assess either the Studio 590s or A190, but I will say, the Revel F208s seem to integrate nicely with the RC263 (initial test tones sound indiscernible from each other - I haven't hooked up the C205 yet, but will try it soon - I remembered it being less 'dynamic' than the RC263). It's not a perfect setup yet, but currently running the Revels with the main HT system, and I've worked in 4 subs (four corners of the listening area). The f208s sound amazing... haven't A/B tested them (subjectively) with the stereo system sitting next to them yet (Ariel 10T, Sugden Masterclass preamp, Topping D90, Auralic Aries, and March Audio purifi amp), but I'm expecting them to be more linear in music mode -obviously, but probably not as dynamic as the rock concert, house sound of the Ariels.
