Developed from Grand Prix Audio's standard APEX design we now offer these outstanding silicon nitride balls as upgrade balls for the Monaco Turntable and any other sensitive audio application such as, CD players, preamps, amplifiers, and speakers which all benefit greatly from this product. Silicon nitride balls outperform traditional steel bearing balls due to the tailored material properties and finishing allowing these balls to have exceptionally tight tolerances and smooth surfaces. The excellent surface finish allows silicon nitride balls to improve overall performance.
This unique cup/ball geometry utterly avoids the frustrating instability that plagues other bearing-based designs which cause supported components to wobble and move when barely touched. Threaded "knuckle" adjuster/levelers securely surround the ball bearing with a polished stainless steel cup.
The common diameter of the ball bearing allows the end user to experiment with a variety of bearing materials readily available in this standard 0.5" size (ceramic silicon nitrate, Tungsten carbide). Music lovers with substantial investments in conventional high-mass metal stands reap significant dividends by "floating" these structures on the Apex devices. While incapable of approaching the performance of complete thru-engineered isolation solutions, such an upgrade provides a very cost-efficient means to drastically improve the poor self-damping characteristics of metal stands that are really vibration transmitters (think bells) rather than isolators.
