I agree that it would be best to try the Marantz SA-10 and Esoteric players before buying (new or used). But there are only a small handful of Marantz dealers in South FL and haven't found one yet that as the SA-10 on display that I could listen to.
@fauguy , have you considered Music Direct? I believe they still sell them (that's where I got mine) and they do offer free shipping to you with a 60 day audition period. (I assume if one decides to send something back that Music Direct does not pay the freight for shipping on that end of the deal.)
