Kuzma - Stogi Ref 313 VTA - 9" Reference Tonearm w/ VTA Tower
The Stogi Ref 313 VTA, 9" tonearm by Kuzma incorporates the same conical tube, vertical bearings, highly damped brass housing, and detachable headshell as the Stogi Ref 313. Additionally, it features a precision VTA (Vertical Tracking Adjustment) tower.
This is a very rigid, medium mass tonearm with precision ceramic ball bearings. These bearings display extremely low noise levels and starting & running friction. The main frame and all other parts are machined from solid aluminum or 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.
The headshell is secured with a unique hexagonal locking system, giving the same rigidity as with a fixed headshell. The electrical connection is via standard pins but the headshell can be easily removed by unscrewing with a hex key.
A decoupled brass counterweight controls the balance and adjusts the tracking force, while damping vibrations in the tube. The conical tube is machined from a solid aluminum rod and is internally damped. The tube is divided into two parts which also allows for precise azimuth adjustment. A worm-drive mechanism, operated with a hex key, allows the tube to be rotated back and forth in minute 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 frequent adjustments.
The massive arm base serves to clamp the tonearm rigidly to the arm-board. All bearings are pre-loaded and glued into position. This creates a long-lasting, zero-play bearing with low friction and low noise.
The whole construction is mounted on a rigid VTA (Vertical Tracking Angle) tower which allows VTA adjustment while playing, without any loss of rigidity, yet with up to 0.01mm of precision with zero play and repeatability. VTA adjustment is made by raising or lowering the tonearm into the arm base itself.
Internal connection wires are continuous from cartridge pins to output connectors. High quality wires are incorporated into our own cables. Output connections are available in: 5-Pin DIN, RCA or XLR (Balanced).
NOTE: USA sales and shipment only. This product is special order. Tonearms do not come with a cartridge. No cables are included with DIN Tonearms. Some Kuzma items ship from overseas, so delivery times may vary. Accordingly, delivery may take 4-6+ weeks. For questions about availability and shipment, please contact Sound Approach.
