No experience here but have come close to purchasing a few different Esoteric players on Audiogon before. I find your post interesting. Wouldn't it be great to have the ability to audition various pre-owned players in our systems, so we would know what to buy and what not to buy? It's such a crapshoot unless you buy from a dealer that allows auditions. But, to save money we buy here at the Gon and pay the cost of sometimes shuffling and reselling components in and out of the house.
