Actually, chances are that the potentially slightly warm and rich sound found in most Rotel amps would compliment nicely with the potentially slightly cool sound found in most ProAc's.
You might consider a used Sony 777es player for about $1200 to $1500. Or you might even consider a used Sony DVP s9000es SACD/CD/DVD unit for about $600 or so. And then have the unit modified by Stan Warren for $250 for an even better sound.
Both Sony units are very well constructed and offer superior off-the-shelf performance for their original retail prices.
-IMO
