Cartridge "demagging"

Hi Bikeman: I own the 90X and the Sumiko fluxbuster. First than all: why do you want to use the fluxbuster with the 90X? Is there something wrong with it quality sound reproduction ?. How many hours of use has the 90 X?. Please let me know about all these issues.
Now, in the time, I use the fluxbuster in severals cartridges an as a fact I only hear a difference in the sound ( high frecuency ) with a Koetsu Onyx Gold. I can't hear any differences in no other cartridge and I can tell you that if this fluxbuster don't help it not do any harm at all.
Regards and enjoy the music.

Raul,
Just for your data points, our Shelter 901 had about 500-600 hours on it when we played the Cardas LP. It had started sounding a bit muffled, lifeless, lacking in dynamics. You know how the bass on the 901 sounds in cold weather if VTF is a bit too low? This was similar but all frequencies.

The Cardas LP's de-mag sweep woke everything up like a slap of after-shave on a sleepy face. We didn't change anything else, so it was either that record or magic beans! ;)

I've never tried it on another cartridge. Do you think it would do anything for a 20 year old ADC XLM?!

Dear Doug: I can remember that I try the Fluxbuster on my
Astrion and I don't hear any changes.
You can try in your XLM and " see " what happen. I have no experience with the Cardas record and I don't know if it is for MC and MM cartridges. I tell you this because in the Fluxbuster when you use it with and MM/MI cartridges you have to do it with out the cantilever/stylus mechanism.
Regards and always enjoy the music.
