Vertere Super Groove Precision Tonearm (HB)

 

Super Groove Precision Tonearm HB

Benefitting enormously from the work done in developing the Reference Tonearm, the Vertere Super Groove PTA HB offers incomparable performance in almost any class.

To achieve breath-taking musical performance, the Vertere SG-PTA HB utilises a combination of quality materials including roll-wrapped carbon-fibre, stainless steel, brass, aluminium alloys and silicon nitride. Its unique bearing design and versatile anti-skate adjustment make it an ideal partner for highest quality cartridges and turntables.

• Custom Pulse HB internal wiring

Vertere Reference Tonearm is a milestone in vinyl replay. Its design, build quality and attention to detail have provided us with performance that is second to none. Of course such quality comes at a price.

It was only natural to ask if by a parallel, albeit different, approach to design could we develop a much more affordable tonearm that was similarly capable of breath-taking performance? This was the beginning of our journey that has led us to the introduction of our latest Vertere Super Groove Precision Tonearm.

At first sight the SG PTA Tonearm may come across as a uni-pivot, it is in fact anything but a uni-pivot. A uni-pivot will ‘skate’ about on its bearing point of contact while the tonearm moves side-to-side and up-and-down. This is because there is no such thing as a point; there is in fact one surface supported by another and sliding relative to each other.

And because of this there is always some ‘skating’ of the contact point on the support bearing surface. Although the ‘skating’ or ‘chatter’ may be in fractions of microns but so is the magnitude of some of the information stored in the vinyl groove. 

To eliminate this ‘loss’ of information due to unwanted bearing chatter, we have designed a Tri Point Articulated bearing or TPA. Three silicon nitride precision balls and a precision machined pivot point provide the support and the articulation for the arm. Although the tonearm may appear to behave as a uni-pivot, it is however, without any of the bearing ‘chatter’, preserving as much of the signal information as possible. The result is a life like dynamic response with unexpected clarity, musicality and detail – truly unparalleled.
