hi there, I'm an extremely frustrated imbecile when it comes to hooking up my marantz system sr 6300. I have had numerous people who tell me they know what they are doing configure it but none can get my system working properly. I have reset the unit back to factory defaults and now can get no sound at all. Any body got any idea's, I can't make any sense out of the manual and am very close to smashing the thing to pieces. I would appreciate any input on this problem.
