I can't comment on the specific Bedini device because I have not used it.

However when the Bedini Clarifier was originally introduced in the US, I led a blind audition comparing its effects with an "unclarified" CD.

In fact I did not "clarify" any CD's, but listeners often thought I did -- that was caused by their overactive audiophile imaginations. Read that sentence again and think about how it could affect audiophile recommendations.

Many A-B differences "heard" in audio are only imagined -- our "audio memory" is a very short term memory ... and audiophiles are pressured into believing differences among components are almost always audible. That belief is a very important part of the audio "religion" -- however under blind conditions audiophiles often can't hear differences that they had claimed to hear minutes earlier in a "warm-up" audition ... before the identities of the components were hidden (blind audition). I've done this myself and witnessed it many times during double-blind auditions.

No materials used in the CD (polycarbonate and aluminum), except for possibly some inks that could be used for some labels, can be magnetized. Therefore, demagnetizing a CD is not feasible.

In my opinion the product is likely to be a complete waste of money.
I've been an audiophile since 1966 and have built speakers & subwoofers as a hobby
since 1971.
