The essence, heart and soul of the SAFIR 12 tonearm is an extremely rigid, conical arm tube made out of sapphire - the first of its kind and the first implementation of the precious stone for this purpose. The overall rigidity and resilience to all unwanted resonances are key natural properties of sapphire. As such, it outperforms any arm tube used in any tonearm, remaining resonant free up to 5 kHz frequency. This gives the phono cartridge generator a true "ground". Owing to the natural density of sapphire, SAFIR 12 tonearm has to have a considerably high effective mass.

SAFIR 12 bearings are the same as with the Safir 9 tonearm which are a further improvement over a solution already found in all Kuzma 4Point tonearms.

The sapphire arm tube is fitted into a massive ensemble of solid aluminium and brass blocks, providing an extremely inert and mechanically quiet support to the arm tube itself. A twin section brass counterweight with a lock mechanism accurately balances the tonearm. Azimuth can be adjusted in small, accurate and easy to repeat increments with zero play (using an Allen key).

The new Kuzma SAFIR 12 tonearm fits on the 12 inch Kuzma cut mount position. We have developed a special VTA tower for this tonearm, which is a part of the armbase. Accuracy and ease of repeated adjustments are possible in a simple and effective manner.

The SAFIR 12 has a special silver alloy internal wiring as standard specification. A single, uninterrupted cable connects the phono cartridge between the headshell pins and high quality RCA or XLR connectors at the opposite end.
