Best cleaner is soap and water. I use drop of car wax to really clean them good. I rise them in warm water and use a micro towel. Many new good CD releases, and as far as sound quality of mastered well superb. I love vinyl but nothing wrong with CD. Don't follow the trends,many great recordings,in the CD format, thousands in my collection and counting. I do own a excellent SACD player though, the K-O1. The new Marantz, is very good also. I liked the physical formats and I have no disire,to burn them or MAQ just so the can get you to rebut and get stuck with another format. 99% if listeners enjoy streaming radio, portable phones etc. Billions of downloads, Hundreds of million CD sales still and 10's of million vinyl, so something for everyone.
