That's something: My DVD / SACD player SONY jumped increasingly at SACDs, so I already thought to have to get him for repair. But first I wanted to try a cleaning CD. I have the CD tricked three times for 20s, and lo and behold, the player plays SACDs as new. No more dropouts. I have the mini-brush (also) still moistened with a few drops of isopropanol from the pharmacy. Perfect!
