I think something like 50 percent of the information stored on a cd is a security system to stop people from copying mass cd's. Supposidly you can copy one cd to one cd but not one cd to a hundred cd's.
All of this extra info creates a lot of problems including timming errors. As stated by Garfish the jitter device will reclock the music.
I use a digital lens and I like it quite a bit. The only thing to understand is that this is a tweek and will not make an explosive difference. It will add a lot of faint nuances, clean up the sound a bit, and will make a positve difference.
