Why would you use the 5.1 channel in instead of the CD player analog inputs ? If I have the CD player connected to the CD Player In jacks am I converting from analog back to digital and then to analog again in the 1050 ? I think this is the case from what I have read on this board but I want to confirm this.

I am curious what CD player you have that has a better DAC than the 1050 ? How good of a CD player do I need to buy to get a better DAC than the 1050 ?
