The new Sapphire cantilever solution
Multiple studies show that demand for strategic natural resources continues to increase. New technologies use ever-increasing amounts of rare and strategic resources. Understandable that this increasing demand may complicate future supply.
Over the decades, there has been an increase in the use of Boron. Elemental Boron is mostly used in high tech applications. One of Boron’s benefits for our modern technology is its use in neodymium magnets, which are an alloy of neodymium, iron and boron. Boron has also been applied in manufacturing of phono cartridges: Boron cantilevers are strong, stiff, light and 100% inert. From all possible options Boron cantilever is the best, but unfortunately extremely difficult to obtain.
To make sure future supplies of the Ortofon High-End cartridges, we will henceforward reserve the use of Boron cantilevers for our Exclusive series.
The new MC Quintet Black S model is graced with Shibata stylus on the Sapphire cantilever. Sapphire is one of the best cantilever options that provides an excellent mechanical pulse transfer from the stylus to the coil system.
The Quintet Black S, like its predecessor Quintet Black, produces detailed and pure reproduction though-out the spectrum, volume and soundstage.
