Final update...
The Focals are now running on my system, on the exact same positions my Revels were.
Very surprisingly enough, the Revels seem to have more bass, but it's probably all midbass. Bass extension is actually somewhat similar, which surprised me. The Focals may go a bit deeper, but not much.
They are able to handle pretty much all the power I could give them. They can definitely go louder than the Revels.
Having said that, I was as surprised as how different they are from the Revels, and how alike they are. Both are great, great speakers. Both have terrific mids. Both have amazing dispersion. But the Revels are a bit darker, have a bit more midbass, and a bit more recessed midrange.
The Focals are far, far more open, and highs seem more present, but never aggressive. The midrange is just perfect. I've read publications where they recommend "tuning" them with different components, and cables. LOL. If that's your objective, just get an EQ.
While the Revels are more laid back and easy going, the Focals sparkle and sing. I just love the way they sound. Really love them. Had I listened to the Revels and the Focals side by side, I'd probably still have picked the Focals. But its personal preference, and I'd definitely understand if someone preferred the Revel sound. On a given day, I would, too.
The looks... they look like fine furniture, while the Revels look like cool speakers. That's one aspect where the Focals are simply far above the Revels.
I wouldn't have gone wrong either way, though. I did love the Revels darker nature, and the louder midbass and, I guess, low bass. I love the Focal and their lighter, clearer sound. Either one is a slightly different particular interpretation of neutral. And both are among the finest speakers I've ever heard.
Thanks for all your help! I really appreciated it.
