Demagnatizing a ZYX Cartridge

Rauliruegas,

I used to own a Sumiko Blue point years ago, and a Benz Glider after that. Both of those cartridges benefited from using a demagnatizer. The cartridges seem to lose some of the top end of the music and after demagnatazation the highs seemed to be restored.

Dear Doug/slowhand: For I can demagnatizing a phono cartridge first I need that some of the critical cartridges parts/build were magnatized and in today cartridges there is no single part that " suffer " the magnatized effect.
So, why have I to demagnatizing something that are not magnatized?

I already ask to some cartridge builders like: Ortofon, Dynavector, Van denhul, Allaerts, Koetsu and Clearaudio. The answers was the same: their cartridges doe not needs demagnatizing, because there are no parts to demagnatizing.

All these similar answers confirm my statement/question.

Now, all of you " hear improvements " after the demagnatizing ( I believe you ) but I think that you are doing more harm to your cartridge that helping it.

Maybe what is happen is the same that happen when you clean/polish a gold metal chain that is dusty: after the clean/polish the gold metal chain really " shine " again but that gold metal chain loose a little of the gold metal ( with each and again clean/polish )and is loosening its original value ( price. less gold content ).

Regards and enjoy the music.
Raul.

Raul,

What damage do you hypothesize could be done by playing a 30-30K Hz frequency sweep? Our cartridges play these frequencies every day. The only difference is that the sweep covers every frequency in a minute or two. How would that harm a cartridge?

OK years ago I owned a ZYX--before they were imported to USA. Loved that cartridge. An occasional demag improved the sound of my cartridge.

But.................the instructions on the demag suggested to try multiple passes of the demag cycle. Makes sense, no? One pass improves the sound, try another cycle and see if there is further improvement. This I do not suggest as it fried my cartridge.

So, do your demag, but please be careful.

Tubes108,

What kind of demagnification did you use. Active device? Cardas record? Or...?

Many thanks,
Doug
