As the title says I am starting to research a newer AVR. My current is a Yamaha RX-V1600, do not get me wrong I do like it I just wish it had some better features. When I am ready I was thinking about getting one from accessories for less ( its better than e-bay plus at least there is a warranty ). I want to stay between 400 to 600 and depending on the AVR maybe 650 ( Yamaha RX-Z1 ). I do not favor any particular brand without getting into high priced units the three I am most interested in are Denon, Marantz, and Yamaha. To be blunt I have no clue about the latest and greatest auto set-up? or GUI etc. I would like good clean sound at least to me the higher current amps sound the best. I have read good things about all three some say Denon sounds better than Yamaha I do not know so any input on what you guys think is a good AVR would be great.
