If you go to Audioreview.com and research your player you will see that the unit has a history of skipping and down time. If isolation devices and proper leveling/cleaning and adjustment do not work it may be time to move on (unless it's under warrenty). Sorry, I am only the messenger. I passed on one of these for next to nothing a while back due to its repair history.
cd player skipping
While playing cd's from an NAD C540 cd player I'm hearing alot of skipping, jumping and breaks in the the music that are forcing me to stop listening. I keep my cd's clean (I don't touch the surface), and I clean the lens with one of those cd Lens cleaning disks. Nothing seems to work. I could use some Ideas. Thanks.
