Estimated Value of Old, Nice System?

Rega Planet CD player, circa @1997--2000, Yamaha HTR-5830 Receiver(2009) and two PSB 300 speakers with towers. Come with all necessary wiring, Yamaha remote and solid, heavy black playing stand. (I've had these ten plus years, the system sounds great & in fine condition, but they just too big for my new, smaller home).

Purchased from another audiophile: can anybody out there suggest even a reasonable market value?
