What should I sell these for used here? Buyers?

I have the below speakers, and receiver... used, but for only about 200 hours... GREAT shape. EXTREMELY impressive system... being an audiophile (obviously)--I found that these speakers were about as good as it gets, before you have to start spending obscene amounts of money. Was about a $4,000.00 system back in '11 when I bought it... haven't used it at all, and need to get rid of it. I actually have a passive 3D 1080p 65" LG LCD from the same year I'm also trying to sell... was WORTH (spent less) $6,500.00 when I got it... it's also THX certified. Should I sell everything together, somewhere? Where? Do you think they would sell here? Certainly wouldn't on craigslist. Should I sell them together? What should I ask?
