Kuzma Stogi Reference 313 CE Gimbaled Tonearm

A 12″ version of Stogi Ref tonearm with a unique rigid but detachable headshell, and with a VTA option

This is a very rigid medium mass tonearm with precision ceramic ball bearings which withstand very heavy loads while offering extremely low starting and running friction, as well as low noise levels.

The main frame and all other parts are machined from solid aluminum and brass blocks. Some parts are anodized and some are not, in order to help control tonearm resonance. The detachable headshell provides a stable cartridge mounting, while the internally damped tube connects this to the massive bearing parts where any vibration or noise is dispersed. Most parts are glued together for rigidity and damping.

Detachable Headshell

The electrical connection is via standard pins but the headshell can be simply removed by unscrewing with an Allen wrench. The headshell is fixed with a unique hexagonal locking system, giving the same rigidity as with a fixed headshell.

The conical tube machined from solid aluminum rod is internally damped and divided into two parts which, while further aiding damping, also allows for precise azimuth adjustment. A special mechanism (worm drive), using an Allen wrench, allows the tube to be rotated back and forth in minimal increments with no air gap. This mechanism is submerged in silicone grease for further damping. A marker line clearly shows the azimuth position and facilitates use, while allowing for repeated adjustments.

A decoupled brass counterweight controls balance and adjusts tracking force, while damping vibration in the tube. The massive arm base serves to clamp the tonearm rigidly to the armboard. All bearings are pre-loaded and glued into position which, while damping vibrations in them, also provides long-lasting, zero play, low friction, and low noise level in the bearings. VTA adjustment is made by raising or lowering the tonearm in the arm base itself.

Wires are in one length from cartridge pins to RCA connectors. It is also possible to use the tonearm in a balanced ( XLR) or 5pin configuration.

Comes with Cardas Copper wiring and ETI Copper Bullet RCAs. Includes mounting collar for non-Kuzma turntables ($180 value).
