Thank you all so much for your responses. I was taken aback when I called Resolution Audio for their input on this matter. Their response was, "the db25 cable offered by Ridge Street would not be worth the money, after all, it just passes instruction data and +5V to power the main unit - this could not possibly make a difference." While on the phone discussing the db25 cable issue I asked the question, "Would you recommend the GNSC modification to your player?" Their response was, "we would rather not comment on the mods offered by GNSC." I am assuming that there hush-hush attitude was to protect their company and not stick their foot on their mouth.
Audiobb: the player has no programming feature, but does have a very nice track/disc repeat feature.
