I am planning to purchase a second BDP-83 and am trying to decide if I need to add the optional RS-232 port to the unit. I don't currently have a RS-232 controller, but I do have a Denon AVR-3808ci that also has a 232 port and may want to pursue future options that utilize these interfaces. I'm not sure I will ever spend the money for such a control system (not clear at this point of the benefits of a wired RS-232 system vs a high end IR or RF remote with onscreen displays from the HT components), but I thought I would ask the forum membership their learned opinion of this option before I pull the trigger on BDP-83 #2. TIA.
