Hi, I have a Fisher CA-880 amp that has four inputs. The four input are AUX, Tuner, Tape and Phono. I have my CD player in AUX but soon Ill be adding a DAC. Once I get the DAC, I willl running my cd player digital to DAC and my computer thru USB. Can I use the AUX on my CA-880 as an input from the DAC? Thanks
