Unipivot Bearing logically thought out
In the genuin audio point, the unipivot bearing in the upper part of the arm is composed of different ball bearing elements. The geometry is adapted to precise guidance in the horizontal plane and to exactly one fixed pivot point.
The bearing tip consists of an adjusting screw with a welded hardened bearing ball. The centre of this sphere is the centre of rotation of the tonearm, which remains invariable in every position of the entire tonearm.
The bearing is absolutely play-free and yet extremely damped. The feared ‘unipivot tilting’ is thus avoided. Instead, the tonearm displays a high degree of mobility, flexibility and non-inertia in the rotary movement. The excellent horizontal guidance results in an extremely clear spatial presentation of the vinyl reproduction.
One of the core beliefs of genuin audio is the need to avoid any form of sound-coloring external influences. Therefore, the joint of the tonearm to the drive is extremely stable and low-resonance. The height-adjustable upper part of the arm is guided and effectively damped via a particularly massive M8 thread and three O-rings. The tonearm top has two extremely low-lying counterweights. These are mounted for adjustment to different kind of cartridges. These weights carry out the basic adjustment of the tonearm. The exact adjustment of the tracking force is effected via the central weight.
“The point is the uncompromising development of a tonearm I designed in 1978. All the experiences of the years and several hundred development projects since have been incorporated into the work and make the point what it is today.”
Carbon and Aluminium
The tonearm is made of carbon, since this material combines lightness and stability in an ideal manner. The headshell of the tonearm genuin audio point, which is bonded to the thin-walled tonearm tube, is made of aluminium. The relatively high weight of the headshell contributes to the stiffness and ensures maximum mass inertia in the area of the cartridge. Again, it is also necessary here to avoid unwanted signal influences, because of resonance as an example. This approach continues in the inside of the tonearm.
“…a tonearm that provides best tracking with a variety of cartridges…”
To minimize the number of interfering solder points and signal interrupts, the tonearm cable is wired through. It leads directly from the four sockets on the pickup connector to the connector for the drive. This is a high quality plug from LEMO. The genuin audio drive also has the LEMO connector.

Press comments on the genuin point
“A perfect single-point tonearm that purposely eliminates the pitfalls of this principle. … For a uni-pivot tonearm, the imaging precision and the clear focus of the point are probably unique. … Regardless of the price tag, the thoughtfully designed and easy-to-use tonearm presents itself on a par with some of the finest exponents of its kind.”
