I'm either going to get a 5-disc or a 400 disc changer. I have heard good things about the Sony ES line. If I use the digital connectors from any CD player, does it really matter what kind of DAC's are in the player itself. Won't the sound reproduction be based on my receiver? Would I be better off using the 2 channel output from the CD player? If that's the case then is it worth the extra money to get a Sony ES CD player? Any other recommendations would be greatly appreciated.
