I'm thinking of selling my Pioneer 504HDE as we have sold our house and will be moving to a rented apartment in Canary Wharf. It's about 18 months old and has done 3,500 hours. The media receiver and display are in perfect condition with no screen burn, although the remote does show some small signs of normal wear and tear. It would come with the PDP-S12-LR speakers, a PDK-WM01 wall bracket and a PDK-TS04 stand, all the original boxes and manuals. What could I expect to get for it? There may also be the opportunity to purchase an AX5i receiver and speakers but first I will need to determine how much they are worth.
