how much?

[admin_exported]

hey guys, im going travelling for a year around australia and new zealand as a well done to myself for finishing uni, but i will be leaving my set up at home which i know will not be used once. So i have already said that my girlfriends parents can have my tv while im away, which i great but im then stcuk with my denon 2310 and B&W theatre set up with upgraded 685's as rears and the 610 for sub with 30m QED Evo airlock plugs doing nothing. What would be the typical price to sell that for as if its not good i would rather keep it in storage for my return, although the extra money would help. This isnt me saying its for sale, its just a question of what would be the going price and worth thinking about.
