I have a Sony 300-disc changer that I'm looking to connect to my H/K AVR225. It has an optical digital output and analog outputs. I'm not sure which to use since I'm not sure what the difference would be. Am I correct in assuming that using the digital cable I use the DACs in my receiver and using the analog cable I use the DACs in the CD player? (The same sort of question applies to another scenario, where I have a DVD player with Burr-Brown DACs. If I hook this up with a digital cable to my system, am I still getting the benefit of the Burr-Brown circuitry?) Thanks.
