Value inquiry - Martin Logan Motion series


I'm looking to sell my current setup, but have no idea on what it's actually worth. I've spent some time trying to find other used sets, but came up empty handed. I put it up for sale and haven't gotten any inquiries so my assumption is that my price is too high based on actual value. Any insight would be appreciated.

Martin Logan Motion 12 pair - 8/10 condition
Martin Logan Motion 8 center - 9/10 condition
Martin Logan Motion 2 pair - 9/10 condition 
Denon X2000 receiver - 9/10 condition
128x128ebaquero10
I was hoping that I could get about $1000
Wish you were in Australia, we’d have to pay over a $1000 just for the Denon 150w x7.1 Reciever.

Cheers George
Well, I've had a hard time selling the speakers as a set, even at a price drop to $650. I'm assuming that at this point, I should sell them as separate speakers (Motion 12 and 2 as pairs). Does anyone disagree with that?
