Can anyone tell me about CD demagnatizers?


Do they make a difference? If so what sort of difference do they make? Are they worth paying say $150 for?

Thanks,

Bulk tape eraser from Radio Shack works better and cost is about 30 bucks. Hold eraser about 1/4 inch from CD, hit the button and slowly move the CD away from the eraser about 3 feet and you're done. Makes a noticable difference in the sound. Try it, you'll like it!
I have the Bedini Ultra and the RS bulk demag unit, but don't use either on a regular basis. Any improvement is very subtle. The very expensive Furutech unit is supposed to be the best demag available for CDs, Cable Co may let you try one if you are interested. There is a review in Stereophile on the Furutech, also at 6 Moons:
