I'm not sure what DAC's the 5005/6006 uses compared to what's in your SR6014, but I'd be willing to bet you couldn't tell the difference. You probably know this already but the DAC's in the CD player will only come into play if you are connecting it by analog RCA cables and will not come into play if you connect the CD player via Optical or Coax digital.
On another note, it looks like your an avid hiker, and I am as well. Attached is a picture from my Sierra trip this past August.
