I could use some help here. I have a 3K budget, a Denon 4802, 2 Polk subs stacked(wife to be hates the size of them together), and the upgrade bug bitin' my butt. I looked at the Rotel today and I like it. Now, do I get a 5 channel amp and use the 4802 as a preamp? Do I try to find a 7 channel amp? Do buy the 5 channel and a seperate 2 channel amp? Do I sell the 4802 and buy a preamp and an amp? Do I just buy an amp and a small Carver sub? Do I buy the 5803? I'm puzzled. Perhaps I should do nothing? Where the heck do I find these choices in L.A.?
