Technology

Building on the critically acclaimed SG I PTA, the Super Groove II shares its sibling’s aesthetic style, but has evolved in almost every aspect of its design and performance. The SG II PTA achieves a groundbreaking new level of balance, precision, and connection with the record surface - a perfect upgrade option for owners of the SG-1 and RG-1 record players.

It may look similar to the SG I PTA, but Super Groove II Pathfinder Tonearm shares only three components with its sibling; the fine tracking force weight, the lift lower mechanism, and the silicon nitride triple bearing assembly. Every other element of SG II’s design and build has been carefully recalibrated to improve upon the SG I, and yield performance levels as close as possible to the flagship Reference Tonearm.

Weight distribution has been fine tuned to optimise the effective mass seen at the stylus tip - significantly reducing movement whilst elevating efficiency and information retrieval. To do this, key improvements have been made including a new titanium headshell that achieves better dynamic mass distribution, and a heavier dual-axis counterweight that's decoupled and fitted with adjustable outriders for enhanced azimuth adjustment. A new bearing yoke aligns even closer with the stylus tip, and a stiffer rolled carbon fibre tube improves the connection to the headshell and bearing yoke joints.

These, and many more nuanced improvements, mean the SG II PTA delivers an astonishing amount of musical detail - elevating the performance of your entire analogue source.

Features

Tri-Pivot tonearm bearing
The unique Tri-Pivot bearing consists of three super-round silicon nitride balls, with an aerospace-precision Tungsten Carbide pivot at its centre. The pivot point centred between the silicon nitride balls provides flawless support and articulation. The new Tungsten Carbide pivot is made and polished similarly to the RG-1 record player’s main bearing to deliver exceptionally low friction and noise.

Carbon fibre tube & headshell
Roll-wrapped carbon fibre is used to construct the arm tube, delivering a more robust structure. The new titanium headshell is optimised for dynamic balance - connected to the arm tube using a new, structurally improved bonded alloy end insert.

Bearing yoke and Stainless Steel pillar
Tungsten Carbide bearing pivot is bonded to a new precision-machined aluminium alloy yoke. The pivot point and the counterweight’s centre of gravity are critically positioned relative to the stylus tip for super improved dynamic response.

Fine-tracking weight adjustment
An adjustable and decoupled stainless steel ring provides ultra-fine tracking weight adjustment. The relative position of this ring and the main counterweight can alter the arm/cartridge resonance frequency, optimising the cartridge's playback performance.

SG Tonearm Pillar Holder and Clamp
The precision machined stainless steel pillar is held in place with a new, high-precision pillar holder and clamp to improve rigidity when coupled to the record player.

Internal Wiring & Contact Connectors
The cartridge tags and the 5-pin connector pins are designed, machined, and gold-plated to Vertere’s specifications. The 5-pin connector main body is CNC machined from solid PTFE for its superior dielectric characteristics. Internal wiring utilises Vertere’s Pulse HB super-fine conductors.

Bias-curve adjustable anti-skate mechanism
Anti-skate can be set variably across the record – for example, variable increase from the outside to the inner. Optimal results can be established by listening at the beginning, middle and end of a record and choosing the best performance across all three positions.
