I am looking at purchasing a new A/V Receiver as a first step to move into the Digital Age. High on the list are the Sony STR-DA4ES, Denon AVR-8302, Denon AVR-1082, and Marantz SR5300. The sales persons at Tweeter have been pushing the Denon 1082 and it looks nice, but steer me away from the Sony (won't even help me listen to it ). I don't have the surround speakers yet, but will move in that direction as soon as funds allow. Budget for receiver $500-650. I just want some more reliable input on the choices out there, whether mentioned above or something else you really have found to work. QUESTIONS I HAVE: 1)I have concerns over Denon's warranty and post-purchase customer service. How is Sony's service (I know their ES line has 5 year warranties) 2) Must you buy Sony's at authorized dealers to get the valid warranty (as is the case with Denon)? 3) Does the 4ES really have separate channel volume AND tone controls (and how do you access it)? 4) What is the link and download I have read about that some 4ES's need for a decoding problem? see following link; Sony 4ES problem with decoding DTS-ES That's enough for now. Thanks in advance for the help.
