Iv'e Seen the D-stat (that little gun thing) and have thought about getting one. Not sure if it would do any good.
How does one get their paws on a magnetic tape bulk eraser. Is this a one time shot or do you
need to redo every so often? Guess I could just send the 400+ cds to you Dave and when could
ya get back to me?

That is one I have. Performed an exorcist of those nasties yesterday and was very pleased with result. Just sounded better overall. What ever sibilants were present [ hardly any or none to begin with] with vocals is now completely gone, gone, gone. Cleaned up top end big time.

Id like to understand in more detail why is there an improvement after demagnetizing a disc?

I'm not sure there is a whole lot of detail to it. Magnetic fields on the disc can cause a "bend" in the laser light path whick can result in the reflected light not missing the photo sensor and certain bits not being read properly. If the magnetic field was static it would not be a problem as the photo cell could be adjusted to compensate for the4 bend, but since the discs is spinning, that means the magnetic field is moving around and the displacement from the intended laser path out be random in nature causing data errors.
Nick, using this device accomplishes the same thing as the Bedini Ultraclarifier.just not automatically as you would need to hold down the power button on the demag unit and move it around by hand.
And if you do use one of these devices be sure that it is always moving while it is on and move it at least an arm's length away from the CD before letting go og the power button t the sudden collapse of the magnetic field will re-magnetize the disc (or at least that is how it worked when we bulk erased reel to reel tapes when I worked at the radio station.
