Kuzma 4Points and Lyra carts

FWIW "I think" the 11 will outperform the 9 and I hope the 14 will outperform the 11 because my 4 point 14 will be here next week and the difference in $$ is substantial. Everything you read says longer is better

Currently have a DP6 and a DP8 both with 12 " blue dot arm wands. so I'll report back whether the 14 outperforms the Morch. 

I might disagree about longer being better. Theoretically, yes it should. But others in the know like Michael Fremer have said the differences are not that great & that a well setup 9"arm will perform as good as a well setup 12" arm  There will be differences but like most everything it is a trade off. Maybe you will like the trade. Maybe not

Either way, I hope you both well with the Kuzma. It is on my radar as well. Then I listen to my TT and ask...why? Hard decisions

Agree with @artemus that there might be small differences but the 9" will be easier to setup than either the 11" or 14". Both longer arms will require VERY precise alignment, not saying the 9 doesn't just the 9" will be easier. 

Agree with @artemus that there might be small differences

define "small".. ..are you speaking from experience or from what you’ve read?

seems to me if the goal is to be the best that it can be then you are potentially leaving something behind if you "settle" for the shorter arm. As I started down the path of higher end arms - tables - cartridges I found that there were huge differences as you get into the upper levels and you are well rewarded for taking the time to precisely align it all. Feel free to come back at me with... define "huge" :)

I agree if you don’t want to invest in the proper tools and spend the time to optimize the setup then stick with the easier path, but if your are "going for it" then go for it with the longer arm. Of course, I will be comparing a shorter Morch with a longer Kuzma so nothing definitive will come of that in regard to whether longer is better (or worse) or if it is Morch vs. Kuzma.

Thanks for the replies.  I especially look forward to @herman report after his time with the Mørch. It’s a great arm but will not be surprised if the Kuzma does even better.My table will do best with the 212mm mounting distance of the 4point and 4point 9. The 14 is not an option.
Let me focus my question. Will the higher effective mass of the 4point 11 work better with the Etna SL? 
I will use the resonance calculators online but I suspect both arms are within acceptable range. My bias is to use a 9” arm as my ears don’t seem to be effected by the increased grove distortion inherent in a shorter arm. On the other hand, I do have excellent setup gear (SmartTractor, Adjust +) so I am able to cope with the precision setup needs of a longer arm. If anyone has listened to Lyra/Kuzma  combos that would also be helpful. Will also use a SoundSmith Sussurro ES.
