I'm looking at buying a bottom line rotel or B&K(RMB-1075, RSP 1066,if this is bottom line?).I have no clue what to look at or if this would be much better then what I have(denon 4802R).I'm on a tight budget of around $1300.Can I do better than what I have for that?I'm happy with 5.1 and I have a paradigm reference system.Can someone give me some advise.
