Kuzma 4Points and Lyra carts

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! 

Excellent Karl!  I'd be very interested in what you think the Sussurro sounds like in comparison to the Lyra. I recommend the 4 Point 9 a lot as it will fit on Sota turntables. I have not heard of anyone not loving it. 

I think this arm is bringing out the best in both carts without erasing their individual character.  I'm hearing increased musical details and clarity and an uptick in dynamics compared to the Mørch.  The Lyra Etna SL has its trademark expansiveness on top while the Sussurro is a more neutrally balanced cart. I feel the excitement when the Lyra is mounted and I tend to forget about the cart and listen to the music with the Sussurro. All these changes are subtle of course but the cumulative effect of hearing more of the recording is very nice. I attribute the later to the great engineering of the Kuzma 4P9 arm. 

Kuzma 9 on my radar for my SOTA, please do keep us informed as you enjoy the music ;-)
