I'd been experimenting with homemade p/c's made by a friend of mine who swears by them. I put one on my Classe CDP-1, it worked well at first, then I went on a 2 week vacation. When I returned, the cd player kept shutting off. I would turn it on, it would play for 10 minutes or so, then shut off. I forgot about the p/c. I contacted Classe and they sent me an RA#. To make a long story short, they could find nothing wrong with it. They shipped it back, I've been using the stock cord ever since, no problems. I felt stupid for shipping the unit and waiting a month, when I should have tried to switch the p/c in the first place.
