digital glare - problems/solutions

I had to take my cd transport out of my system for repairs a couple of weeks ago. i plugged in an old Proceed Transport and the subsequent glare drove me to distraction. To make a long story short i discovered that i had moved the power cord from the dedicated digital outlet in my power conditioner to a regular outlet. Reconnected it to the digital outlet, glare gone. Yeh, i know, i'm probably the last person on earth to have figured this out. Now i remember why i bought the power conditioner for the source components.
