• The 4Point 14 construction includes a zero-play bearing configured on 4 points.  The 4Point 14 tonearm has an effective length of 353mm (14-inch), an exact VTA adjustment facility, and fits a Kuzma standard mount 340mm pivot-to-spindle distance.  The heart of the design is the unique 4-point bearing. Two points (similar to a uni-pivot bearing) allow and control vertical movements of the tonearm. The other set of two bearings allows and controls the tonearm's horizontal (lateral) movements.  All four points of the bearing have minimal friction and zero play in all planes of movement, thus ensuring that the cartridge platform and the cartridge itself follow the grooves of an LP with extremely low friction and minimal vibrations. 4Point 14’s main section is firmly connected to a very rigid and inert VTA tower, which allows fine adjustments of the vertical tracking angle when the tonearm is stationary or while the LP is playing.  All this, of course, without any loss of rigidity and with 0.01mm adjustment accuracy with zero play! The arm also includes two removable headshells that are designed with rigidity intact. From Edward: Recent events using a two-arm table allowed us to compare the differences between the 4Point and the Stogi 313 with VTA tower using Ortofon Bronze cartridges on each arm tied into one source. The 6-panel verdict that included two non-audiophiles was that the delta was vast upwards of half.   
  • The 4Point construction includes a zero-play bearing configured on 4 points.  The 4Point tonearm has an effective length of 280mm (11-inch), an exact VTA adjustment facility, and fits a Kuzma standard mount 212mm pivot-to-spindle distance.  The heart of this new design is the unique 4-point bearing.

  • The 4Point 9 is two inches shorter than the 4Point tonearm. Its 9-inch length and lack of VTA tower make this tonearm lighter and smaller, thus capable of fitting on most suspended turntables. The 4Point 9 is constructed with sapphire/ruby cup bearings and a detachable headshell. From Edward: I have first-hand experience mounting this arm on the Stabi S and Stabi R with excellent results! The tonearm's job is to get out of the way of the cartridge, and the 4Point 9 arm does a good job of that. 
  • This is the 12-inch Stogi Ref 313 tonearm version with fully adjustable VTA tower mounting on a standard 9-inch position. The Stogi Ref 313 VTA tonearm shares the main features of Stogi Ref and 4 Point tonearm, i.e., precision ball bearings, a conical tube, and a unique VTA tower. General description: This is a very rigid medium-mass tonearm with ceramic ball bearings that withstand heavy loads and display low starting and running friction and 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, 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 removed by unscrewing with an Allen key. The headshell is fixed with a unique hexagonal locking system, giving the same rigidity as a fixed headshell. The conical tube machined from the solid aluminum rod is internally damped and divided into two parts, which, while further aiding damping, also allows for precise azimuth adjustment. A unique mechanism (worm drive) using an  Allen key enables 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 repeated adjustments. From Edward: High-performance results and a fun arm to use. It is hard to beat for the dollar. 
  • The Kuzma SAFIR: The heart of the tonearm is a very rigid and stiff sapphire conical tube, which allows the cartridge to perform to its maximum potential. The bearings are our unique design of 4 spikes set in sapphire cups similar to those used in 4Point tonearms. All four points have minimal starting and moving friction and zero play in all directions, thus ensuring that the headshell with the cartridge moves precisely and with minimal vibration across the record. The sapphire tube is fitted into a massive block of solid aluminum and brass, giving inert support and further dissipating vibrations during playback and bearing motions. The counterweight with a lock mechanism balances the tonearm. Azimuth and VTA can be adjusted in small repeatable increments with zero play using an Allen key. The tonearm is fixed via the Kuzma arm base on the turntable arm board. VTA is adjusted by raising or lowering the tonearm’s pillar in the arm base with a VTA screw which controls its height, thus still allowing precise VTA changes when required. Internal wiring is of superior special alloy silver wires.  A set of 4 wires runs unbroken from the cartridge pins via a 1.5 m long tonearm cable with silver RCA or XLR connectors. SAFIR shows your cartridge's ultimate potential and will effectively reveal music hidden in the grooves, giving you a new record collection! From Edward: Audio-Ultra was one of two recipients that received the Safir upon its arrival in the United States. Upon setup, this arm immensely lowered the noise floor, bringing a more comprehensive range of clarity and life to our record collections. This has been proven at many listening events with clients and audio industry representatives. Low-compliance cartridges are better suited for this tonearm. I highly recommend purchasing this arm if you're into analog and can budget The Safir. Wait time is approximately six weeks.
