It is SO easy to prove whether this thing works or not. Won't someone please do it!

All the claims about the success of this device that I have seen are based on a before and after hearing of the same record. Of course you must use the same record, but memory is not 100% reliable. A well-made CD-R will easily have the quality to demonstrate the degree and type of improvement claimed for this device. So, make a CD-R before and one after of the same record. Observe the 24-hour rule, if you are a believer in that. Now you have the ability to go up and back between the before and after as many times as you wish, at any volumes, on any players, whatever. You could even very easily (dare I say it) do a DBT.

If you doubt that a CD-R would the accuracy or capability of making a copy of sufficient quality for this test, I would say you just have not heard how good a CD-R of a record can be. I have used them to decide between record mats, whether to leave the dust cover of the TT up, down, or off, to choose which tubes to use in a phono stage, and to evaluate various TT support mechanisms. I find the CD-Rs to be virtually indistinguishable from the original LP, and in blind listening, many people can't tell which is which. It is claimed by some (e.g., Fremer) that this device makes a really big difference. This would be easy to document with a set of CD-Rs.

Incidentally, somewhere I did see a measurement of the surface magnetic fields of a vinyl record before and after treatment with this device. The fields did go down about a factor of two, but they were incredibly tiny, and that was at the surface. Seeing this data led me to believe that this device can't have any effect on the sound, at least not for the advertised reason, but my mind is open and I would love to actually hear for myself, but do it right: make CD-Rs
