This is One set ZYX OMEGA-S/SB2 with Silver Base. This Cartridge coil is 5N Silver 0.24mV Low Output MC Cartridge , made in Japan by ZYX. ZN Premounted.ZYX OMEGA are built in combination with all utmost grade materials to straightly deliver audio signals as they were generated. With ZYX OMEGA you can feel the original analog sound never experienced before.Lapis lazuli Balancing WeightLapis lazuli Balancing WeightA spherical object fixed to the front nose of ZYX OMEGA is a balancing weight to accord the sweet spot of the cartridge body and the gravity point of vibration system. Having checked up materials and repeated audio monitoring, a nonmetal Lapis lazuli ball having hardness 5.0, specific gravity 2.5, diameter 8mm, and weight about 1 gram is put in at the most appropriate position to form the best cartridge structure. The Labis Lazuli ball used in OMEGA’s other advantage is centroid control. Due to its composition blended of a few kinds of sodalite having spherical shape, vibrating wave flown from the north pole of the ball is absorbed in the crystal architecture mingled inside, and vibrating wave running down the ball surface is finally cancelled at the south pole of the ball.15 items in generatorZYX only succeeded in development of a MC cartridge which does reproduce original stereo sound with a perfect sound balance between the left and right channel.2 Layer Laminate ArmaturesWe made the armature structure have double layers, facing each other with opposite polarity, namely one laminate to face N-polarity and the other S- forming mutually reversed phase positions in order to short-circuit and simultaneously dissolve both eddy-currents generated in each armature.K18 Gold Solid TerminalsMaximum quality 18-karat solid gold matches sapphire terminal board and gets rid of sound coloration unlike conventional plated terminals. Those are apt to create coloration against subtle output signal in micro ampere order due to battery effect between heterogeneous metals.Sapphire Ternimal BoardSapphire Ternimal BoardThis non-metal mineral is hard next to diamond, and has been employed as OMEGA’s and DIAMOND’s terminal board to lock up output terminal pins and statically holds the unit against any sorts of extraneous vibrations.
