GRADO CARTRIDGE & TONEARM COMPATIBILITY


Hello all. I am wondering if the Grado Reference Master cartridge would be a good match for my Rega RB300 tonearm as far as compliance, tracking, and resonance are concerned. Your opinions and experience are appreciated. Thanks.

Greetings to all, 

I recently got a Grado Platinum3 to use on my Graham 1.5c tonearm.

Almost immediately, I noticed that the cartridge and arm would appear to “shimmy” on certain recordings.  After doing some research, I found out about the “dreaded Grado dance.”  I guess this is what is going on.

Before the Grado, I had a Benz Micro Gold on the arm.  It never had a problem.  The Benz Gold weighs 5.7 grams, and the Grado weighs 9 grams. I never thought of the Graham arm as particularly finicky, but maybe it is.  
 

When I first installed the 9 gram Grado, balancing it and dialing in tracking force was not easy.  Dialing in the tracking force just about maxed out the distance I could unwind and push the counterweight to the rear.  (I ended up adding extra mass to the counterweight.) 
 

I am starting to wonder if all of this is going to be the case with any 9 gram cartridge?  Is the “shimmy” or “dance” particular to Grado cartridges? 
Am I limited to cartridges that weigh less than 6 grams? 

 

Thanks for any responses.

The shimmy is most likely due to a peculiarity of the Grado suspension interacting with the tonearm. So no, I don’t think you need to worry with other cartridges.
