Kuzma 4Points and Lyra carts

I think it’s worth noting that some arms probably deal with vibrations and resonances better than other in the same effective mass range.  Those arms are probably more flexible when it comes to cartridge compatibility.

Karl, in regards to the Lyra cartridges the 4 point 9 is the best choice. The 11 will work but the 9 will undoubtedly have less distortion because of it's lower polar moment of inertia and I think you can get a feel for that in the reviews. Both arms will be a significant improvement over the Morch. You will notice an improvement in bass detail and power.

Sussurro is low compliance - 10microm/mN

Thanks @dover! Not sure how I missed that!

Dear @karl_desch  : ""  I think it’s worth noting that some arms probably deal with vibrations and resonances better than other in the same effective mass range.  ""

Yes, sometimes better than other and sometimes just different.

You can analize the Reed 3P that's too a very good design and comes with removable headshell where its EM ( cocobolo or ebony ) is almost the same as the Kuzma 9.

That's an alternative you can thing about and where you will be safe too:
