A few questions for you on the RSX-1055. 1 - How do you like the RSX-1055? Any problems with it? 2 - I see that there has been multiple upgrades for the RSP-1066. Is the RSX-1055 treated the same way? 3 - Does it have DD-EX? 4 - How well would this work? I would like to reassign the front L/R channels to power the rear backs and then use my Rotel RB-1080(2x200)amp to power the front L/R. Anyone do this without problems? 5 - How much does it cost? 6 - Anything else I should know? Thanks so much.
