I stumbled on a way to "A/B" the DAC's in your DVD player vs. the DAC's in your receiver when playing audio CD's: 1. Connect your DVD player conventionally using an optical or coaxial connection. 2. Connect the analogue L/R outputs from your DVD to the CD inputs of your receiver. 3. Play an audio CD on your DVD player. 4. Using your remote you can now switch back and forth between "DVD" and "CD". 5. When you select "DVD", you are listening to your receiver's DAC's. 6. When you select "CD" you are listening to your DVD player's DAC's. You should probably choose either "Stereo" or "Direct" mode when doing this. You may find that your CD's sound better one way or the other, especially if either your DVD or receiver has better DAC's.
