Phd - I agree. When I sold off my first system back in 2003 during a divorce, everything sold quickly - Maggies, ARC's, Musical Fidelity, Blue Circle - everything. Granted, I was living in the Baltimore/DC area and so the population (and money) was tremendous, but this was also pre-recession and pre-digital/Netflix/iTunes/music server era.
And I remember getting asking price or close to asking price for every component. In fact, when I was moving up the line and selling off a pair of Rogue Audio M180 monoblocks, the buyer simply paid my asking price with the note "I'll take 'em...". No haggling, no low-balls.
Now, it seems things take a while to sell and the first few bids are always humorously low. By humorously, I mean 50%-65% of the asking price.
