On paper they appear the same. I love the fact that they have Burr-Brown DAC's and DCDi. The thing that bothers me is, what are the differences? Onecall has the 6480 on sale for $539(MSRP is $599). Are they like the difference between the Yamaha HTR and RX-V receiver line? these players look very good to me. Would anyone like to aslo say whether they would take this over a Denon 1600?
