Stogi S

This is a 9 inch tonearm with unipivot bearing design with a unique, rigid round headshell made from a solid aluminium block and a base of solid brass which control all vibration and facilitate stability of the tonearm as a whole. All parts of the arm are machined from blocks of solid metal, in order to provide damping and minimise resonance. The polished pivot point is sited in an oil well, which provides extremely low friction and bearing vibration. The bearing height is at record level for optimum tracking. The silicone damping controls resonance of the cartridge and also gives stability in azimuth direction.

Stogi S 12

This is a 12 inch version of Stogi S unipivot tonearm.It is a unipivot bearing design with a unique, rigid square headshell made from a solid aluminium block and a base of solid brass which control all vibration and facilitate stability of the tonearm as a whole. All parts of the arm are machined from blocks of solid metal, in order to provide damping and minimise resonance. The polished pivot point is sited in an oil well, which provides extremely low friction and bearing vibration. The bearing height is at record level for optimum tracking. The silicone damping controls resonance of the cartridge and also gives stability in azimuth direction.Two counterweights allow easy adjustments of tracking force and azimuth. Fine azimuth adjustment is achieved by rotation of a horizontal screw in the main counterweight, which does not affect other tonearm parameters and which makes fine azimuth adjustment very simple.Wires are in one uninterrupted piece from headshell to RCA phono connectors. By pre-order, wiring can also be fitted in for balanced ( XLR) connection.

Stogi S 12 VTA

This is a Stogi S 12 inch version tonearm with a fully precise adjustable VTA tower fitting on the standard 9 inch tonearm distance. The Stogi S 12 VTA tonearm shares the main features of Stogi S & Stogi S 12 and 4Point tonearms, i.e. a unipivot bearing, headshell rigid construction and a unique VTA tower used in our best tonearms.

The whole construction is mounted on a rigid VTA tower which allows VTA ( vertical tracking angle) adjustment while playing, without any loss of rigidity, yet with up to 0.01mm of precision with zero play and repeatability.

Tonearm fits standard size turntables, so there is no need to replace the turntable to experience the advantages of a longer tonearms and fine VTA adjustments.

Stogi

Unique feature: Most parts are glued together for rigidity and damping. We use very precise stainless steel ball bearings same as used in gyroscopes precisely mounted with zero play and very low starting and running friction and noise levels. Each bearing from factory is vacuum sealed with serial number for quality control. Each bearing’s load is 20 kg. Two are used for vertical and two for horizontal movement.

Stogi Ref

While similar in construction to the Stogi, this tonearm incorporates a conical tube and the vertical bearings have highly damped brass housing. A conical tube is machined from solid aluminium rod which has built in precise azimuth adjustment worm drive mechanism.
Tonearm geometry, bearing, wires and other parts are the same as Stogi and effective mass differs only slightly.

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.

4Point

3.1.5.02.-4point-single-2.jpg

Differs from other tonearms by introducing several new and unique features. The new zero-play bearing is configured on 4 points. The 4POINT tonearm has an effective length of 280mm (11-inch), a very precise VTA adjustment facility and fits our standard mount with a 212mm pivot-to-spindle distance. The heart of this new design is the unique 4-point bearing. Two points (which are similar to a uni-pivot bearing) allow and control vertical movements of the tonearm. The other set of two pointed bearings allow and control horizontal (lateral) movements of the tonearm. 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.

Air Line

3.1.6.01.-air-line.jpg

Is a linear tangential arm incorporating air bearing which ensures practically zero friction in movements, while still maintaining a rigid bearing. The cartridge is thus maintained in a position the same as the cutting head.

The Air Line tonearm is the result of a combination of experience making top class conventional radial tonearms and new research into air bearing technology.

The Air Line tonearm also has a rigid, minimally resonating aluminium structure and is easy to adjust, with repeatable precise VTA and azimuth adjustments as used in our best tonearms.
