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

Thank you @tonywinga I’ll give it a try. 

pguezze-just curious, did you demagnetize your electronic’s or CD’s with the Radio Shack Bulk Tape Eraser?

Originally bought for CD, I now use it on cables and records. Of course it doesn't really demagnetize CDs or LPs, maybe it is something to do with static electricity I don't know. The effect on CD fades out a lot over about 15 minutes. With LP this is just about right for a side. 

I don't use on electronics because of the way transformers work, if you get very close to one it induces current, you can easily hear the hum. It does the same on all wires of course but transformers have lots of windings, so I avoid them. Tubes have another problem in that the alternating magnetic fields can cause the filaments inside to vibrate, you can hear it. So I avoid them. 

Another factor is the Radio Shack unit is designed for intermittent use. It gets hot and has a thermal shutdown. After some trial and error I figured out what to do and how much and how often to sort of optimize the whole thing. Some might say this is a lot of work for a pretty small payoff. They'd be right. For them. But not for me.

@millercarbon thanks so much for the detailed explanation. As always, very informative. 

agree with the static electricity analysis. There is nothing magnetic about a CD disc or CD player that would cause magnetism. We are not talking about a medium with any magnetic properties. I doubt that a laser beam would be affected by relatively low magnetic flux, but static electricity (high voltage) yes. Just a hunch here on my part.

It's the label side of a CD that may cause magnetism. Ink uses various metals in its composition and ink is used to make the label. 

Here’s a curious aside. I unfortunately had no luck with the Ayre’s disc, But as bad luck occurs in pairs, today we’ve had a power outage locally, now going on for the past seven hours. In response I hooked up my Honda generator to power the house. It can run the essentials at home during an outage, which includes the stereo equipment and computer, and supposedly produces a perfect sine wave..

Out of curiosity I played Joni Mitchell’s Blue CD again which I’d used to test the Ayres disc. With the generator running the album sounded remarkably good. Her voice and the instrumentation sounded more clear, well defined and detailed than ever before. I was kind of hoping the Ayre’s disc might have an effect along these lines. I then tried out Coltrane’s Live at Newport and replicated this listening experience.

Having a Shunyata Denali power conditioner already in place I wouldn’t have anticipated much of a difference with a different power source, but go figure.. I needed someplace to express this oddball listening experience. Sorry for intruding on this fine thread.
