Thanks all. I will try these "maintenance" suggestions on the CDP. Not to string out this thread but I did switch out the Cambridge for a Sony DVD/CD player I had in the home theater. Twice last night on start up of a disk or track I heard a brief burst of this loud static-like noise. It's like a rapid. ripping noise or machine gun fire...not music - just some kind noise. I shut down volume and stopped the disk. It did not return on re-start and did not occur once a disk was playing. I'm thinking the DAC is losing lock but am not sure why. Thanks again for your input. I'm going to switch digital cables next.
