To complement the common elliptical cut, a hyperelliptical needle shape was developed – also known as “line contact” in technical jargon.
The contact zone of the hyperellipse to the plate groove is three to four times larger than in the conventional elliptical diamond cut.
This design distributes the pressure in the plate groove more evenly, thus reducing premature wear of the diamond and vinyl.
In addition, these diamonds are usually significantly reduced in mass and are carefully polished. This also enables better reproduction of higher to highest frequencies, as this cut follows even the finest deflections of the groove more precisely.
The prerequisite for the use of hyperelliptical needles is that
- the pick-up is geometrically correctly mounted by an expert
- the pressure on the platter and the anti-skating are precisely adjusted
- The tonearm bearing is in perfect condition and has no play.
If these things are given, nothing stands in the way of the sound.
