OP hears a positive experience, but it goes against generally accepted audio law.
Responses reinforce why.
Yup, sounds about right.
Sumiko Flux Buster Demagnetizer
Greetings
While I was reorganizing my shelves in my audio room I relocated my Sumiko Flux Buster. Haven’t used it in years. So I demagnetize my 2 MC cartridges and my passive SUT. I was amazed at the improvement of the clarity of the music. I have been using the Cardas test album the last few years to degauss the system. Side 1 tracks 2a/b/c frequency sweep. Seems to work well. The Sumiko worked much better on the cartridges and SUT.
Are others still using this device or similar devices? I’m glad I relocated the Sumiko. Will start using it more for MC cartridges.
