You get the best prices by selling the items yourself on Audiogon, The only thing you have to do is to vet the buyers properly.
Besides, Audiogon has a fantastic support (thank you Tammy) and you support the site for using it.
The Music Room is Slipping
I cannot recommend doing business with them any longer. They DEEPLY lowball you when you sell them gear and then forget all about the mass profits they made on you when you are looking to buy something from them, They offer to stand behind a purchase, yes... but the reality is that it is all about max profits on used gear and lack of any sort of support or consideration going forward. They are nothing more than a pawnshop for audio gear and I am done with them.
