I thought the more interesting statement was:
"All electronic parts (resistors, capacitors etc) contains small amount of magnets."
I've sent them an email asking for a reference for that statement.
I wonder how parts without iron, nickel, or cobalt can have magnets?
Are their other materials that can be magnitized?

Um...do you have reference to what you are talking about here?

[CynicalSkeptic]

Well, since this is the Commentary section, I'm guessing he's referring to this article (http://www.randi.org/jr/2007-03/032307hope.html#i6) in the most recent commentary. And contains this link (http://www.musicdirect.com/products/detail.asp?sku=ADENMAGIC) which contains the quote provided.

It is possible the original statement was a corruption of "All electronic parts when carrying electricity create a magnetic field."

...and in addition to iron, nickel, and cobalt, aren't there some rare earth metals that have magnetic properties?

ETA: Now having seen the original article, I can see the author is just nuts.

The author, who is trying to sell the CD may not be nuts, just selling a product that cannot work. The people who are nuts are the ones that buy the CD.

Well, I'm going to take my electronics degree and toss it in the shredder. This is a revelation!

If you want a really noise-free system, however, I suggest demagnetising the speakers, whose field strength is far higher than anything generated on the PCBs. Demagnetise those speakers and just listen to that glorious stereophonic, noise-free, distortion-free... silence.
