Best Amp & Pre-amp combo for under $2000 ???

I am making baby steps in my system and looking to upgrade to separates. I tend to be around 60-70 percent music. i am using Def Tech's 2006 speakers. I am leaning toward a Rotel setup, cause i've read good things about the natural warm sound Rotel creates. and especially the performance per price. Are there any other companies or combinations i should look at for my taste? any suggestions welcome. thanks in advanced....
