Premium OMEGA

premium omega

The world's first High-speed generation system
Eddy currents which occurs in generation system raises the magnetic impedance in the circuit and affects to the transient response of the sound signal, and as a result, the reproduced sound is badly deteriorated. Eddy currents which occur on a pair of opposite pole faces (N pole, S pole) reverse phase each other. There should be a solution to eliminate such eddy currents.
However, ZYX has discovered that there are two pairs of the eddy currents existing in the magnetic circuit and therefore, it is necessary to neutralize and eliminate these two pairs of the eddy currents at once. The “Premium” series cartridges are equipped with a new “Balanced type eddy current elimination mechanism” which we developed to solve this problem, and succeeded to reproduce an accurate time axis of the sound signal by non-magnetic impedance.

Employment of a new suspension wire
The new material which was not thought about in the past are developed one after another. One of them is a thin and tough material while being flexible.
The suspension wire of MC cartridge is to hold and position the fulcrum of the rotary vibration of the cantilever, and a hard metal wire like piano wire has been commonly used conventionally.
Instead of a hard metal wire, we employed in Premium series new optimal material without aging, tough and of superior temperature characteristics. This brought an improvement in tracking ability and a sense of pitch that soaks into a soul. As a result, the true analog sound of Premium series was further improved in the sense of reality.

Lapis lazuli Balancing Weight
A spherical object fixed to the front nose of Premium 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 generator
ZYX 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 Armatures
We 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 Terminals
Maximum 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 Board
This 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.
