Best place to sell an amp.

US Audiomart....avoid Craig’s list, full of tire kickers and those looking for something for nothing. BTW, I’ve sold on Audio Mart many times. I suggest a full load of photos, showing the packaging too. US Audiomart reminds me of the way Audiogon used to be.

Lately, I sold a six month old pair of 1.7i Maggies, for just a little less than what I paid for them(brand new at Ovation). The buyer(who lived 150 miles North and was my first response) was debating on/balking at ordering a pair, never having heard Magnepans prior. When he saw my ad on Claigslist, he jumped on the chance to hear them. Not one bit of haggling.  Never did list them elsewhere, not wanting to have to ship. That and too many others want too many pieces of one’s pie. eBay even takes a percentage, of whatever you charged for shipping costs. I’ve sold a number of things on AudiogoN, but- not in quite a while. Everyone’s experience will differ, when it comes to selling used stuff, through diverse means.

What cal18 said +1, where-so-ever you decide to list.

IME, lots of low ballers and scammers on Craigslist. Had a $400 item, was offered $50. 
Also listed an expensive item and got a form letter response from a dealer... "we buy anything."

US Audiomart is free and I have very good interactions with members.
