Every couple of years technology advances to the point where a complete conversion from an old technology to the new one is necessary. The device pictured here is a CD/DVD player that can store 400 discs and access any one of them in a matter of seconds. Today I removed my 300 CD music collection from this machine and “ripped” (transferred the digital music content) to the hard drive in my computer. At 5 minutes per CD, it was a time-consuming project but I now have house-wide access to the uncompressed files through the Sonos. The next step is to sell the disc carousel on Craig’s List.
