Demagnatizing a ZYX Cartridge

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

My Benz Aethetix demag suggests trying multiple passes and I have in the past with a Glider and some Grado cartridges without harm. However, after reading this thread I'm not so sure this device is what I should continue to use in the future. I now have a Benz M2 which I just bought so I want to make sure it lasts a while and stays at peak performance levels. Any suggestions out there for the best demag/degausser tools to use?

I'll also be at RAMF this weekend so I hope to learn more about this topic and possible solutions there in addition to what I can learn here.

Dear Doug: My experience and answers from manufacturers were for the active devices.

I don't know about the Cardas passive device.

What I know, active or passive, is that the question has to be answered by the cartridge manufacturer. Not a dealer not any one of us.
The cartridge manufacturer is the person that has all the know how about and in particular about his cartridge.

+++++ " How would that harm a cartridge? " +++++

You don't know for sure, the cartridge manufacturer has the best/safe answer. Not you.

Regards and enjoy the music.
Raul.
