I would not bother trying to upgrade a D500, unless maybe you are doing the work yourself as a hobby..
For the money you could get for it used ($200 to $250 on eBay), plus the cost of some outside person doing the mod work, you could go buy a new Cambridge Azur 640C player..
BTW, There is a modded D500 for sale right now on Audiogon for $300 obo. Get that one.
