well,
as one who likes a bit of empirical evidence (even if only subjective) more then speculation and conjecture i am currently listening to a copy of st germains tourist which was held over the back of my computer monitor while the degauser went off.
if there is a difference then it's well within the bounds of being psycosomatic as it's vanishingly small if there at all. therefore i declare the cd demagnetiser to be audiophool bollox of the 1st water and award it the golden horseplop.
of course it may work for you....:JOEL:
cheers
