Ive just been reading in a UK magazine about demagnetizers.
Now i can at least understanjd how these could be effective on vinyl, after all the cartridge is generating magentic fields and eddy currents that could be affected. But how in the hell can they state that CD's are affected ? improving bass and clarity be magnetizing a plastic disc ? the CD either provide a 1 or 0 full stop, there of course is loads of things happening afterwards that affect the DAC, flutter etc that all could have an effect. But it is just ridiculous that magentizing a plastic disc could affect the sound of a digital signal.
This type of thing gives hifi a bad name.
