I have an old vintage receiver and I'd like to hook up both a CD player and my phone and I pods. The receiver only has one aux setting so I have to keep switching between rca cables and the rca to 3.5 jack for the phone. It is a pita so my old CD player just sits there unused. Is there any CD players out there that allow a digital source in and then out to the receiver? Or any other way to do this?
