Recommendation for Cartridge for Technics SL-1200G?

the Cadenze Bronze is excellent.

I’m surprise that people are recommending the AT Art9 as it is a high compliance cartridge and when fitted to the Technics arm will give a resonant frequency of 6hz which is too low? 

Technics arm effective mass 12g 
Art9 weight 8.5g
Compliance 18x1.7 at 10hz

resonant frequency - 6.4hz

too Low! 

Michael Fremer said of the 1200G...

In case you were wondering if the arm was tailored for high compliance moving magnet cartridges, I can tell you that I used, among other cartridges, the Lyra Etna SL and when I measured the horizontal and vertical resonant frequencies using the Hi-Fi News test record, both measured between 8Hz-and 9Hz, which means yes, you can use the SL-1200G with your favorite low-medium compliance moving coil cartridges.

To calculate what is best there are two resources I have been using. First the Ortofon guide and chart here...
https://www.ortofon.com/support/support-hifi/resonance-frequency

The shows that resonant frequency should be between 7-12Hz is best idea being somewhere is the middle of this range.

For the Technics with an arm mass of 12g +a headshell which is likely to be 7-10g the arm mass will be in the range 19-22g 

This means that Compliance rating of 10, 15 and 20 are best suited (low to medium) 25 is marginal.


This calculator enables precise values of resonant frequency... http://www.resfreq.com/resonancecalculator.html

For this the target extremes are
19g - 7Hz - 27CU
22g - 12 Hz - 8CU

So this shows that between 8CU and 27CU depending on precise cartridge weight.
The optimum probably is 9-10Hz
19g at 9Hz gives 16.5 CU
22g at 10Hz gives 11.5 CU

Two real world example

Soundsmith Zephyr Star MMIC 
Compliance 10 µm/mN
weight 12.2g
On the Technics arm this gives a resonant frequency of 10.2Hz

A 2g heavier head shell would give 9.8Hz


Dynavector 10x5
Compliance 12, Wight 7.3g
On the Technics arm this gives a resonant frequency of 10.46Hz 

Both are good matches!

Many SL-1200G owners are using the ART9 with outstanding results, me included.  When I plug the numbers in to the Calculator I get a value of 8Hz.  Close enough.
