I currently own an Adcom GCD-750. Will there be a difference if I buy a Yamaha universal player ($1,000) and a separate DAC for 2 channel music or should i buy a dedicated cd player. I can't connect a DAC to my Adcom because it doesn't have any digital outputs. It has a coaxial input so that another source can use its inboard DAC. Any suggestions?

System:

Monitor Audio S6
Musical Fidelity A3.2 integrated
Adcom GCD-750
Audioquest Cables
