Head Grado Reference Platinum 2 The pick-ups Reference Series offer these exclusive features: individually wrapped coils on the lathe. Each pair of coils is derived from the same strand of cable. The electrical contacts are made by means of thermocompression joints and not through the welds. The magnetic and electric circuits are balanced to the point not to require any shielding. The total mass of the generator system is balanced individually in order to optimize the symmetry. The twin-tip stylus This stylus geometry, exclusive grade, is ilculmine of many years of research on the behavior of the stylus in the reading of the groove. This stylus, very expensive to cut and shape, demonstrates a particular aptitude to reproduce the modulations of shorter wavelength with continuity of tracking equal to that of two microspheres perfectly aligned. Its geometry can be identified as consisting of two ball-quarters of 0,006 millimeters, ideally separated to position the contact surfaces at the optimum height on the walls of the groove; is thus guaranteed the full engraving reading without the needle is modulated by the imperfections contained in the bottom of the furrow. The minute spherical surfaces have the ability to analyze every detail on the high frequencies and, for its particular conformation, the twin-tip is insensitive to the alignment of the stylus with respect to the groove and the azimuth loss. Once exceeded positively all the technical tests pickups are subjected to individual listening test. As the smallest flaw in the cut of the diamond in hardness and significantly alters the sonic performance, it only ends this examination that will determine which units will be placed on the market. The sound of a pick-up Reference is unmistakable: the dynamics literally explodes in your listening, without the slightest trace of harshness and a definition of the amazing details; the perspective reconstruction goes beyond all imagination. Generally, after this severe listening tests, more than a third of the pick-ups will be destroyed because it does not meet the tonal characteristics established. This hard, but necessary, selection ensures the high quality standard that has always defined the pick-up of this prestigious series and explains the constant presence at the top of the approval ratings of audiophiles worldwide.
