Your description is way better then what I could come up withI'm partial to a a certain tonality, though I'd struggle to define it beyond 'warm'. I'll say this - the last time I tried putting together a stereo system by myself I went with Klipsch, entirely due to stupid reasons - marketing and the beautiful copper color of their woofers.
Well, turns out, I hate their sound. Bright, almost harsh treble - entirely the opposite of that I'm going for. I want prominent mids, silky vocals and more diffuse treble, low-hitting, powerful but not muddy bass. I don't want the whole stage to be dull or loose it's dynamic feel - viscosity like heavy cream, not honey.
I'm technically useless to describe it much beyond that, I'm afraid.
Thanks to all for their input on this - it's a joy to get more educated minds chewing on this problem with me.
Based on what you say and what I have read about them, I'd agree that the Revels would be your safest choice. As suggested above, you could experiment a bit with an UMIK and REW on your existing speakers, or if you are leaning more toward passive speakers, buy a MiniDSP Flex with Dirac first and see what it does to your existing speakers. If an opportunity comes arrange try to visit a shop to listen to the Revels and some active speakers if possible. By Black Friday you may have decide what you like, and a good deal may come your way to get want you want.
Whatever you decide, I'd suggest you buy something that you like from all aspects, actives may be great, but if you don't like how they look for example, better to look at something else.
