@b_limo When you think about the numbers relative to preowned audio gear...if I list something on Audiogon or a similar site....I'm probably going to get somewhere in the 50-60% of retail price for a less than 10 year old, still in demand, great condition piece.
That means that if I sent it to an intermediary...who will then try to resell it at somewhere in the 60-70% of retail range....there is no way they are going to offer me more than 25-30%....and I pay the return shipping to them so I actually net less.
I see it as a trade off....lower price for certainty and no post sale hassle...for some people it is worth it....for others, not so much.
