New Vertere Acoustics SG-PTA and SG-PTA HB Super Groove PTA series tonearms

Vertere Acoustics has introduced two new Super Groove PTA series tonearms. Both models, SG-PTA and SG-PTA HB, are made exclusively from high quality materials, including carbon fiber, steel, brass, aluminum and silicon nitride ceramics.

The Tri-Pivot mechanism of the tonearms is based on three balls, an acetal retaining ring and a steel tip. The balls are made from the silicon nitride mentioned above. The manufacturer said the Tri-Pivot system helped get rid of vibrations. The tonearm tube is made of carbon fiber. The company used a special roll-to-roll method that made the tube more durable. The shell material depends on the version: the SG-PTA used aluminum, the SG-PTA HB titanium. It is attached to the tube with a special metal insert.

The stainless steel spindle is connected to the aluminum mechanism that supports the tube, the main counterweight and the anti-skating mechanism. Depending on the version, the arm is equipped with Vertere or Vertere HB wiring.

The downforce is regulated by a steel ring on the tube. According to the company, the correctly calculated position of this ring and the main counterweight made of chrome-plated brass will allow the resonant frequency of the tonearm and cartridge to be tuned as accurately as possible for optimal music reproduction.
