Thanks again to one and all. I will report back once I take possession of the D10X and get some time with it. In the end I think it came down to a choice between the Ken Ishiwata (Marantz) voicing, which tends toward lush mids and highs and more forward, versus the Luxman more analytical and more distant perpective. The Esoteric that was on offer was older, used, and I was afraid of it for that reason. Other suggested brands in this discussion were not available to me. I do have the right of return if necessary, but that is unlikely.
