I don't believe Rotel has similar genealogy to Yamaha. I've heard some Rotel amps, (can't remember the exact model) and they didn't sound like Yamahas. The Yammies have a somewhat unique way of being very clear and dynamic without being clinical or fatiguing.
I'd personally stay away from Ribbon and AMT tweeters with a "glassy" room. Might be best to stick with tubes considering your other gear is somewhat forward and bright IMO.
