From searching the archives to find out how others have handled glare in their systems I found that members years ago heard audible improvements when they swapped stock power cords out of their CDPs for aftermarket ones. Some of these threads though were 4-7 years old.
For me when I had an Emotiva ERC-1 CDP and put in a My Audio Cables (MAC) HC Power Cord I heard a quieter background. It made me get off my chair and notice.
Again like Theo said above it is system and person dependent. Part of me believes it is component dependent as well. When I had a decent Sony receiver and put a thick Tributaries power cord on it I heard no difference.
