It is a far harder, and a much softer used market than I have ever seen right now...It's lucky to get anything name brand, or not like this sold for 50% value even 30% of retail is average on a lot of audio these days unfortunately.
If you are that desperate to move it honestly most of this stuff won't move unless you go over to Audiogon, and pay the new ridiculous fee's, or Ebay which does pretty well auctioning stuff like this, but get ready to pay about 150.00 bucks in fee's from ebay, and paypal if it sells for $1200.00 or more at auction, well over 10% to 13% comes out in fee's on total... A few years ago it would cost you about 40 bucks or so to sell something like this, but 3 or 4 times that now....
Not to mention if you insure it, and ship thru Fed Ex, or UPS get ready for the shocker there. Again old shipping maybe 2012 and back you were looking around 25 to 35 bucks fully insured. Now ... Ha, you can pay 50 to 60 bucks to send it across the street with 1200.00 in insurance at this point!
Blue Book is quite useless on most gear as well accept maybe Mcintosh, and few huge legacy brands. For example just like the "Used LP guide" it will tell you that a mint copy of Van Halen's first album is worth $25 to $35 bucks... Good luck getting $12 for it!
