Best place to sell high end audio equipment?

@colinmaken I don't know if that's a good offer, but it's based on supply and demand. They're thinking about how fast they will be able to turn around and sell your gear.
   That Yamaha 3000 is a very nice amp. You may be able to easily sell it on an auction site, but have trouble selling the other items. Take this into consideration with TMR's offer, plus there's no commission or fees. You could counter offer saying you want $4000.

Rodman99999, I am not trying to solicit someone to buy via the thread to avoid commissions.  Paying a commission doesn't bother me at all.  Really all I was looking for was some thoughts on how much wiggle room there was with the Music Room. To me, a "lowball" offer could be anything.   I know some resellers only offer half of what they are actually willing to pay and I don't want to leave money on the table.  It's not about the models I have, its about insight into their willingness to bargain.

Colin, I recently was considering selling an amplifier to TMR.  The individual I dealt with made an insulting offer, justifying it by saying that they would sell the unit for a price far below what they will actually sell it for.  In fact, the amplifier is the newest, recently released updated model, and he said TMR would turn around and sell it for what the older model sells for on the resale market.  This individual has been mentioned unfavorably recently in another thread.  

I am guessing that you are dealing with the same individual and I don't think he will do you any favors and he certainly has turned me off to ever buying or selling anything from TMR.

It appears TMR has black listed me because I haven’t accepted any of their last 10 (or so) low ball offers.  I had asked multiple times to break my offers down individually to no avail. I will fill out the form with 3-4 items listed and they will give me one offer; I don’t know what is being offered on what.  This may be a tactic in order to offer even less.

secondly, their offers have been insulting and they seem to get pretty upset “wasting” their time when I won’t accept their lowball offer.  I would gladly have accepted 35-40% of the retail price for my mint condition, less than 5 year old equipment.  I had no idea that when they throw out that lowball offer that you can actually negotiate with them like the flea market.  

 Anyhow, I imagine if they keep lowballing enough inquiries it will deservingly effect their business in negative ways.  
Be careful about how many lowballs you decline from TMR if you don’t want to get black listed!  If you’d like to keep selling to them, it’s best to take their insulting offers with a smile and say “Thank You” as well!

If you're selling your item to anyone that will be reselling it, you'll inevitably receive less, it's common sense.
Regarding eBay and Paypal fees, build them into your asking price. It's not complicated.
