Kuzma 4Points and Lyra carts

Kuzma 4Point arms require a 40 mm hole for the post.

@factoro2.  Thanks for the clarification!

You might want to check out Galibier Design's website.  They are listing  Kuzma arms on Audiogon.  They have a hybrid option that uses the 4Point 9 foundation and swap in the 11" arm.  It gives a spindle to pivot of 264 mm.  You get the solidity and simplicity of the 9 base along with the 11 arm that has the VTF micro-adjustability.

Thom Mackris at Galibier is great.  I ordered my 4point 9 from him and he had an armboard drilled for me.  Should be receiving both this week.

Well I received the arm on two days ago and have got everything dialed in. I use Wally tools reference, SmarTractor and Adjust plus. 
My initial impressions are very positive.  Working with this arm is a pleasure. Obviously well made and easily adjustable once you figure out what bolt and screw adjusts what parameter.  This thing looks like it means business!

Sound-wise it was immediately apparent how good the arm matched the Etna SL.  Improved clarity, spaciousness without loss of detail.  The overall presentation was as others have described, more of a front row feeling with dynamics and energy.  
I’ll get the A90 and the SS Sussurro mounted on spare head shells eventually.

This was a good move!
