And as far as the 9db boost,just set it and be done with it,its really not that big a deal.
As I recall, the 9db boost was only required while any of the EQ modes (Audyssey, Flat, etc.) are enabled. If EQ is not enabled, the reduction in output is not present. If you are unhappy with the SW level after calibration simply add db as you prefer. If you are enabling EQ modes, add more. SW SPL level is highly subjective and not as critical to match with the other speakers.
I used the Audyssey calibration as a starting point, then manually adjusted all speakers with an SPL meter. I never use the Marantz EQ modes as I don't like the way they sound and run my subwoofer hot (+6db or more above matching).
The only other issue I've seen is the well-publicized DTS-HD bomb which is the loud popping sound when allowing the Marantz to decode the newer dolby audio formats. This is easily avoided by using your playback device to perform the decoding instead, which I've done since I heard the pop once. Fortunately, no damage incurred as a result of the pop.
I do agree that the user setup menus are very cheesy and dated. Around that time, many of the competitive models were starting to have fancier graphical menus, but I figured I would be working in these menus just a few times over the life of the product. That assumption has held true, as I honestly haven't entered the setup menu in over 2 years.
It is unfortunate you (slow ride) have had issues, resulting in damage. That does suck. Perhaps you received one of the few lemons shipped. If you read through this entire forum, you'll find very few complaints regarding this unit.
