As a negotiation point, they are offering an item (4311) that is missing a feature that you find valuable in your current AVR (wireless). Ask for the 4311 PLUS the hardware to provide a wireless solution PLUS maybe $100 to pay someone to set up the wireless solution. This will make you "whole" in the insurance sense. Also point out the the additional hardware is a concession on your part due to space requirements/aesthetics/etc whether it is or not. Look at the situation from their perspective, they admitted liability and want to settle this as cheaply as possible, including their ongoing labor costs to administer the claim. If the 4810 is the current replacement for your AVR according to Denon, what's it worth relative to the 4311, at wholesale pricing? If it's $500, then I'd up the $100 install labor noted above to $200 which when added to the hardware solution for wireless, say another $100, totals $300 and is $200 less than the $500 less than the wholesale marginal cost difference between the 4311 and 4810. WIN WIN. I might even ask for the Airplay upgrade for free, and be willing to give it up as a concession point. Remember, your opening position can only go down, never up. If it's reasonable they won't feel insulted, and you have concession points that won't hurt you and from their perspective will make them feel good I'd they get you to give up something from your initial starting point.
