The Rotel CD players are pretty good little players. The Rotel receivers aren't bad either, but like so many other receivers on the market, the amplification gets the short end of the stick. Plus, Rotel does not have a neutral sound, it can be characterized as being somewhat dry imho. Still, better than a lot of others out there, though.
If I were to recommend a separate amp for the 42's, I would probably direct you to the Parasound Halo A23, it is a fabulous little amplifier that will drive the 42's wonderfully. We've been using the Parasound Halo's with the Dyn's for years now and when on a limited budget, I cannot recommend anything that would outperform the Halo's.
