I just got Paradigm Studio 60's for my fronts, the CC-470 center and Studio 20's for the rear. I need a suggestion for a new receiver or separates. I was thinking Rotel or NAD but I've hear some not so good things about NAD receivers (humming, pops, etc.). I 'm trying to keep the budget around $3,000. I'm also willing to get an amp for now with my HK receiver and get the processor later. Thanks.
