[QUOTE="gbyleveldt, post: 27343, member: 122"] Nope. That is a gross generalisation. With modern discs that are in reasonable condition I've yet to see the error correction algorithm kick in, let alone affecting sonics because of the Error correction algorithm used based loosely on a CRC checksum. This checksum can recover lost data, except if there is so much damage that this cannot happen. In those instances the CDP will mute or start skipping. Nope, taking figures out of context and twiddling them to suit their argument. The optical servo is too far from the actual disk for that amount of ferrous metals to remotely have an impact, should that even be possible. If, for argument sake, there were "magnetism" in the disk it would pale in comparison to the magnetic field created by the servo actuators in the optical system. It's about here where I stopped reading... Sorry Jeandre, I respect the fact that you tried to start a debate about the feasibilty about such a product and accept that it was done in innocense and not trying to push the product. But I just cannot see this as valid, less so at the suggested asking price. [/QUOTE]
