Good point Millercarbon
one other thing to consider is the Marantz actually true balanced or just single ended looking as balanced. True balanced is a lot harder to do and can give benefits in cable cost and ability to run longer runs. true balanced negates many of the issues with cables and EMI as the balanced signal cancel out the EMI more then single ended can. In theory you don't need to spend huge money on balanced cables as they require less shielding.
I'm sure someone here with more background in balanced systems can inject more information and details as to the benefits losses.
