Counselor, I'll file my own brief, although I suppose another one really isn't needed. The problem with assigning the problems you describe to a CD player is that any competently engineered player these days reproduces 20-20Khz with essentially flat response and with inaudibly low distortion. There's no known technical reason for incompatibility with such a component that would destroy these response and/or distortion measurements.
