Accessories4Less has it (refurb) for $1100 shipped. Granted that yours is not a refurb, but you will need to offer a better deal in addition to Marantz warranty guarantee.
Just my 2 cents.
I have a Marantz SR8000 for 7 yrs and a 7300OSE for 5yrs
BOTH REFURBED from AC4Less, both still working beautiifully
Refurbed is actually better than used
Comments regarding someone's sale such as this should be handled via PM. He has a right to sell his Marantz at any price he wants. If he doesn't sell it because he has it marked higher than it can be purchased somewhere else it harms no one but the person selling it (assuming they can't sell it, which he did). By calling him out in his for sale thread, you basically are telling anyone else that's reading this thread that he's a fool, which is not fair to him or people shopping either. If someone is interested in that receiver I will assume they will try to work a deal.
Telling him his price is too high because you can get a refurb from A4L for less is like you selling your car for $5000 but the guy down the street has the same exact car, same miles, same condition with a salvage title selling for $3000. Should you reduce the price of your car even though it has a clean title and the other guy doesn't?
Please use PMs to address price issues, it keeps classifieds much more civil.
