Even I had similar problem with my sr 5007. Last year I sent it to Mz Audio for rectifying HDMI board issues. I got it back after 2 months and many phone calls. They claimed that they changed HDMI board but it seems they did some patchy work only. Now recently my sr 5007 stopped sending audio signals to speakers. I checked with them and they are asking me to send it again for repairs. Once it goes to their workshop, it takes ages to get it back and also you don't get updates from them.I had a bad experience with Marantz sr5008. It was fine for 3 months and started giving trouble. I sent to service center(MZ Audio) couple of times. They said that they replaced all the boards and send back but VB still the problem was there. Transportation was the problem they claim. I fed up with it and after around 6 months I have shown it to local Yamaha service man( Marantz service is not available). Finally he explained me how I was cheated by MZ Audio. They are no connector plugs. All boards are soldered together which is stopping him to sort out the issue.
Seriously this is a big addiction with Marantz sound as I couldn't be happier with other setups such as Yamaha, pioneer,onkyo,nad and even Denon.
I can't give up this AVR nor dare again to purchase one more

Hi
As for me, I run audyssey to check and see what typical settings the AVR does itself based on various parameters...
Then I calibrate manually levels, EQ, source levels etc to get the wow / bliss to my ears.....that's the beauty of any Marantz model, you can tweak as much as you wish...
