Not too long ago I owned Stratos monos and currently own the Bel Canto integrated. At one time or another, I used both on the SF Cremonas and both sounded very good. IMHO, there is zero chance of a noticeable sonic mismatch - although I'm assuming that the Bel Canto monos would match well with their own integrated. I suppose I could be wrong about that since I've never compared 'em.
In any case, both are among the better SS amps I've heard (and both are good value).
