I bought a used pair of the original Revel Studios last year and pretty much went through the same search as the OP. After researching it to death and given my budget, I ended up agreeing with Spinaker that the surrounds were not as critical. I got a pair of S30s and am very happy with the results. They can be switched between dipole and monopole to adjust for music vs movies. The only caveat is that they are on-wall speaks and that they do stick out a bit so you should make sure you're ok with that.
