Has anyone heard the Kuzma 4 Point arm?


Since there is SO much great,original thinking going on in Audiogon these days(not from me)I thought I might scoop those curious folks,and provide some fuel for thought.

I've been following the "word of mouth" about this arm for quite some time.It just tweaked my interest,because it seemed such a novel idea(and I had bought a new arm in the last few months,though a different design)but I knew little about it....Until now!!

This arm has just gotten a "Product of the Year Award" from the latest HiFi Plus(Roy Gregory).He goes on to proclaim this "original" design as a breakthrough in analog replay!!!

I know,a "reviewer's opinion,but c'mon,it's fun! -:)

Now,in case you don't know,Roy Gregory has been thoroughly reviewing some amazing arms in the last few issues,and does seem to know a thing about analog replay,so his incredible enthusiasm for this new "4 Point" arm is eye opening!!

Of course I am very curious about the potential performance this arm can bring to the table,because I am SO enamored with the Air-Line arm,and if this is competitive,we might be able to get closer to a "linear's performance envelope"(though this one is a pivot).

You can download the review on the Kuzma web-site,so have a fun read.

A 4Point was demonstrated at CES with one of the new Kuzma cartridges and will be on demo at the AXPONA show in April.
Yes, it was demonstrated at the CES this past January on a Kuzma Stabi XL. Franc Kuzma was present and showed me one that was cutaway to show the inner workings. It won't be surprising to see reviews by US publications as well. It is very doubtful that Kuzma would ever need to do a Mk II version.

We are going to have the 4Point arm here on the Stabi Reference.

Dealer disclosure.
Rauliruegas, the original Kuzma cartridge was by Shelter. The current ones are by ZYX.
A 4POINT was used on a Feickert turntable at RMAF with a Lyra Skala cartridge, and we are using a Shelter Harmony with the 4POINT here.

The XV-1s compliance is 10 x 10^-6 cm/dyne and weighs 12.6 grams. Comparatively the Lyra Skala compliance is 12x10^–6 cm/dyne at 100Hz and weighs 9 grams, while the Shelter Harmony compliance is 9 x 10^-6 cm/dyne and weighs 8.5 grams.
