If you want something to fall in love with, try Sonus Faber in your price range, or Magnepan plus (optionally) quality subwoofers to extend the bass and pressurize bigger rooms. I have a modest pair of Maggie 1.7 and a pair of small subs to augment them and I'm really happy with the results.
Sonus Fabers have a seductive quality about them. They manage to have a low noise floor, high resolution, excellent power response, and yet always sound musical and never sterile or clinical. I heard a pair of $10K Cremona Ms powered by a $999 Marantz PM8004 integrated amp to great effect, so your Rotel MBs should sound fine with them.
