If you have a CD Player, you need to do this periodically...

I  use the Isotek System Tune Up Disc , it includes a demagnetization track amongst the other tuneup tracks

@charles1dad & millercarbon

Totally agreed there should be fewer derisive comments around here.

My comment was that I used the Ayre disk commended in the OP and did not notice a difference.  Given the cost (assuming you do not buy a dedicated CDP to implement!), I did not disrecommend it, but I'm betting a good percentage of those who try it will have my (non)experience.

(Btw, I don't dispute that "break in tones" could be useful for new speakers; my observation applied to older equipment.)

It will be interesting to hear the new adopters weigh in.

My post wasn’t directed toward you at all. Rather my response was to the ‘wise guy’ snarky comment mentioning the green CD pens. It was an uninformed comment in my opinion.

OK, i'll bite: what is being demagnetized?

@charles1dad 

Fair enough!  I enjoy your posts.

To be fair, Ayre's name for the product invites a bit of fun.

I never used the green pen, but I did use expensive CD cleaners. 

I seemed to have a genius for scratching CDs, and am mostly glad to be done with them (except when my fragile rural internet fails).
