I've had a ton of trouble in the past year with my Marantz receivers. I have an SR7008 in my main system and an SR6009 in my bedroom. I do make them work hard with HDMI - all sources are HDMI and I use both of their independent HDMI zone 2 outputs. However, I've had to send the SR7008 for repair twice and the SR6009 for repair once in the past year for HDMI board issues. The 7008 had the board replaced, behaved for 6 months, and then had the exact same issues started coming back.
I'm convinced it's bad HDMI boards causing the issue especially since the boards have been replaced and the issues fixed (temporarily). Am I missing something? Why are these boards to unreliable? Should I be checking anything else? I've had my TV HDMI board replaced in my main room and tried swapping cables in attempting to pinpoint the problem originally.
Thankfully, these have been warranty repairs, but we all know how frustrating it is to have to disconnect the hub of your system and be without it for a time.
Unfortunately, the Marantz receivers have the unique feature set of outputting digital audio connections to zone 2 and 3 and includling SubEQ HT which is why I used them. Only higher end Denon receivers share that combination of features. If this issue continues, would there be any reason to believe a Denon receiver would be more reliable or about the same since they're the same parent company?
