Yes, it will burn it whether you hear the CD or not.
But, a better idea:
If your amp or preamp uses the same pc connector, it will burn in a lot faster plugged into them. Most cdp's draw very little current, while the other units will draw much more and thusly burn you pc in faster. (My cdp draws only about 35 watts, while my preamp draws 140 watts, and my amps at idle draw over 300 watts and playing loudly can draw thousands.)
