The new ‘Ultimate Exceed’ range of moving coil cartridges from ZYX
Put simply, a moving coil type cartridge can be described as a kind of transducer (a device that converts energy from one form to another).
It induces a current, proportional to the vibration speed in the coil. This is arranged in the direction perpendicular (set off at 90 degrees) to the magnetic field line, by the mechanical movements created by the stylus tip tracking the grooves of the record. This creates and transmits a sound signal. It can be called a converter.
To enable faithful, high quality reproduction, it is critically important that the magnetic flux density in the magnetic field (where the coil is located) is uniform.
In the case of moving coil cartridges, which are currently in widespread use, the bobbin is made from material which has a high magnetic permeability and good high frequency characteristics. This means that the bobbin is highly sensitive and reactive to the applied magnetic field. As a result, this type of bobbin gives a signal six times higher than that obtained from a non-magnetic bobbin. Therefore the number of coil turns can be reduced and the overall mass of the vibration system is lowered, allowing wideband reproduction.
We should note that, by using a magnetic bobbin, the magnetic field and magnetic flux density, which should be uniform, may be disturbed by the bobbin vibrations. This is because the two coils used for stereo reproduction are generating left and right channel signals in a disturbed magnetic field. As the left and right channel coils are arranged so that the windings are off-set by 45 degrees from the vertical axis, the ground terminal positions of these coils are located at different points, separated by the coil length. Resulting from this condition, the left and right audio signals are generated in two different disturbed magnetic fields.
In order to eliminate this phenomenon, it is necessary to set both left and right ground terminals within the same magnetic field. As a result, the left and right coils will generate electricity in the same magnetic field, even when that magnetic field is disturbed.
ZYX are the first cartridge manufacturer to develop and implement this unique, ‘one-point ground terminal, dual output system’ and are therefore able to completely solve this problem.
This new system has been implemented in all of the new Ultimate Exceed models.
Now, with these new models, we can instantly and clearly hear the benefits of the homogenous sound reproduction of left and right channels that have been generated in the same magnetic field. We have natural and sensual sound and a truly glorious analogue reproduction. And the achievement of a true emotional, analogue sound that we have been striving for. Striking, intense transients, sharp focus and localization, we can even ‘feel’ the skin of a large drum resonating as if it were a live performance. The Ultimate Exceed models get us even closer to the real, live musical event.
New Gold-Silver alloy coil wire (G-S)
In the conventional Ultimate series cartridges, there were three coil wire choices – crystal copper, gold and silver.
In the new Ultimate Exceed series of cartridges, there are two coil types – crystal copper and gold / silver alloy.
Although the resistance value of the G-S alloy type wire increases due to alloy processing, you can enjoy the unique, delicate, mellow and wide-band sound that combines the merits of gold and silver.
Diamond Cantilever
The Ultimate DIAMOND utilizes a State-of-the-Art cantilever design using a square diamond rod (□0.22mm). This creates a cantilever of low mass, the highest rigidity and superior dampening that allows the DIAMOND to track and respond to the most dynamic passage with great accuracy and extremely low resonance. In addition, this light and rigid diamond cantilever provides the quickest sound transmission of any material, allowing the fastest time response of the magnetic circuit.
Lapis lazuli Balancing Weight
A spherical object fixed to the front nose of the cartridge 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 Lapis Lazuli ball has another important merit than 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.
Composite Carbon Terminal Board
This world-first hard terminal board has been employed as the terminal board to lock up output terminal pins and statically holds the unit against any sorts of extraneous vibrations.
And besides this terminal board can be grounded to the phono-stage amplifirer through the ground line of right channel output.
You must listen the purest sound by eliminated capacitance between 4 terminal pins.
Cartridge Case For REAL STEREO
Item 11,12 and 13 of the vital design points make very complex demand of the body's electrical properties. Non metallic body which has two kinds of hard material is necessary in order to achieve these properties, and to prevent external disturbances from influencing the generator system and also it prevents eddy currents in the case from effecting the generator output signal and the resonance occuring on the body surfaces.
Super High speed reproduction engine
This circuit is specially processed to null magnetic resistance within magnetic gap, and enables high speed power generation against signals over entire bandwidth straightly without time delay. And besides this circuit can perfectly eliminate any eddy currents remaining at once.
Micro-Ridge Stylus
The stylus used Ultimate series has the edges of the diamond shank set parallel to the sides of the cantilever. Using this type of stylus, the hardest axis of the crystal is aligned to act as the contact point with the record groove. This gives stable and smooth tracing and produces a very refined sound, with the additional benefit of giving the stylus an extended life time 2000 hours.
The stylus is of the Micro-ridge type, which was originally developed in Japan and offers the highest performance. The contact radius is always 3μm by the ridge made with 6μm thickness.
