If you deny that cables change as they are used then of course such a device is nonsense. If you believe, as I do, that cables change as you use them such a device is not silly and could be useful.
Oh and by the way it isnt the copper that changes it is the dielectric. At least this is the theory.
A true audiophile cant get to the music without equipment. Nothing stupid about wanting to get to a certain point as quickly as possible and until you have tried such a device some would argue you should be excluded from this conversation.
I use a Audiodharma device to burn cables in for my clients and am a believer. But of course what do I know I only use a device often and compare untreated with treated cables on a regular basis.
