Stogi Ref 313

This is a 12 inch version of Stogi Ref tonearm.
A special feature of the tonearm is a unique rigid but detachable headshell.

This is a very rigid medium mass tonearm with  precision ball bearings which ( ceramic ball bearings since July 2012), while withstanding very heavy loads, displays extremely low starting and running friction and noise levels. The main frame and all other parts are machined from solid aluminium and brass blocks. Some parts are anodised 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 key. 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 aluminium 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 key, 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. High quality wires are incorporated into our own cable. It is also possible to use the tonearm in a balanced ( XLR) or 5pin configuration.
