Vertere SG-1 Tonearm
Benefitting enormously from the work done in developing the Reference Tonearm, the Vertere SG-1 Tonearm provides unsurpassed performance in its class.
To achieve breath-taking musical performance, the Vertere SG-1 Tonearm utilises a combination of quality materials including roll-wrapped carbon-fibre, stainless steel, aluminium alloys and silicon nitride. Its unique bearing design and versatile anti-skate adjustment make it an ideal partner for any high-quality turntable.
Why SG-1 Tonearm?
- SG-1 Tri-Point Articulated bearing eliminates loss of information.
- Non-resonant, high-rigidity roll-wrapped carbon fibre arm tube.
- Bias-curve adjustable anti-skate mechanism.
- Decoupled stainless-steel main counterweight.
- Adjustment ring for fine-tuning of tracking weight and arm/cartridge resonance control.
SG-1 TPA Tonearm Bearing
The unique Tri Point Articulated (TPA) bearing is comprised of three precision silicon nitride balls and stainless pivot. The pivot point centred between the balls provides flawless support and articulation.
TPA eliminates bearing point ‘skating’ and allows the stylus to track the most delicate pieces of information that are typically lost with uni-pivot designs. This ensures accurate play back due to the strict adherence of the stylus to the record groove.
SG-1 Tonearm Tube & Headshell
Roll wrapped carbon fibre is used in the construction of the arm tube. This provides higher strength and more homogenous fibre structure than a Pultruded or moulded equivalent.
The head-shell is machined from aluminium alloy and connected to the arm tube via structurally bonded alloy end insert. Naturally non-resonant and higher strength to weight ratio of this configuration provides the optimum cartridge platform.
Aluminium Bearing Yoke & Stainless Pillar
The bearing pivot is structurally bonded to the aluminium alloy yoke. The yoke assembly provides the support required for the arm tube, the main counterweight and the anti-skate mechanism.
The pivot point and the counterweight centre of gravity are vertically positioned to be as low as possible. This in turn retains the tonearm in its most stable position.
Arm/Cartridge Resonance Frequency & Fine Tracking Weight Adjustment
An adjustable and de-coupled stainless ring allowed to move along the arm tube provides fine tracking weight adjustment.
The relative position of this ring and of the main counterweight can also be used to alter the arm/cartridge resonance frequency and optimise play back performance.
SG-1 Tonearm Main Counterweight
Attention to detail is clearly seen in the polished stainless steel counterweight and peg.
Two pairs of silicone de-coupling rings are neatly sandwiched between three machined Acetal retainers to provide the necessary grip for location and the required isolation of the counterweight.
Tonearm Lift/Lower Mechanism Plate Assembly
Bespoke components are used for every part of the SG-1 Tonearm. These include its machined Acetal arm clip and polished stainless steel cueing device.
Internal Wiring & Contact Connectors
Both the cartridge tags and the 5-pin connector pins are designed, machined and gold plated to our exact specifications for the SG-1 tonearm. The 5-pin connector main body is also machined form solid PTFE for its superior di-electric characteristics. There are two options available for the internal wiring of the SG-1 tonearm:
