I am now in the same boat that started this thread, so I guess this is as good a place as any.
It is now December, 2015, and my Marantz SR8000 has worked flawlessly since I purchased it in January 2000... just a few weeks shy of 16 years ago! I've been through more cars than I have A/V receivers.
Yes, the technology has changed dramatically in the intervening decade-and-a-half but there has been no imperative to replace this unit (for which I paid ~$1,200, I think, in 2000).
Today the power fluctuated in my house... in rapid succession about four or five times, and (even though the receiver is on a UBS/surge protector) this evening when I went to turn on my system, there was no audio output on ANY channel from the SR8000 from any of several sources, including the internal FM receiver. The displays on the unit would seem to indicate that it's all still working, except for the part where there's no sound...
I suspect the power amplifiers are fried (is it possible for SIX channels to fry at the same time??), and the unit has finally reached the end of its life expectancy. So, assuming this post somehow finds its way to the top of the site, a couple of questions:
1) Can anybody suggest any further "troubleshooting" techniques I might try? I have rebooted (power off/on) several times, to no avail.
2) Assuming it is in fact time to replace the unit, what should I be looking for in an equivalent, contemporary unit? This one has 105 watts on each channel, I think.
3) So... what's new? What should I be looking for in the way of new technology? My primary input device is a TiVo Roamio. Also AppleTV, and a DVD player (never did go for BluRay). The unit is also the head of a Control4 home A/V system, and each device (except the DVD) plays to two output displays, so I need to replicate that capability. HDMI? Everything presently uses separate video and digital audio connectors.
So, that's the story Jerry... every 15 years or so... time for a new audio head end.
Hope somebody can help.
