Can I Degauss my vinyl ?

Don, I instinctively agree with you. But the fact is that the vinyl either does or does not contain ferrous particles that are or are not magnetizable. These are questions that can be resolved, up or down. I am curious to learn whether there is any merit at all in that claim.

As to the "electromagnetic" property of a rotating LP carrying electrostatic charge, if that does happen it ought to be correctible by any good anti-static method, as you suggest. You don't need a $2700 Furutech if that's the major issue.

Demagnetizing anything that does not contain iron is pure hocus pocus. A demagnetizer will not affect (I mean REMOVE) static charges either, although it might move them around.

Same with demagnetizing CDs. They only contain Al (or maybe gold) films that are uneffected by magnetic fields.

Reminds me of that AS review back in the 80's claiming photons have an impact on speaker wire...

Dhl, I think there is unanimity on your major point, if the underlying assumption is valid, but the question is ARE there in fact ferrous materials present in the pot from which LPs are generated? One person on this thread claimed that there are.

Lewm:

You mean iron contaminents in the vinyl? Even if there were, one would have to draw a connection between the amount of contamination and the properties of the vinyl. Seems a very big stretch to me.

As I said, I am and always have been a skeptic when it comes to this issue. But then we have the many who say they do hear a difference before vs after using a degausser. Their collective testimony does not convince me, because of the element of subconscious bias, but it does more or less cause me to try to keep an open mind.
