I have a very nice low mileage ZYX Ultimate Omega MC cartridge for sale. This cartridge has had about 75 hours of use so it is just about run in. It is in excellent condition and comes with a 3 month guarantee from any mechanical or electrical defect. It is fitted with the SB2 headshell so it has a mass of 7.7 grams and comes with 6N’s OFC copper coil wire. I fitted the cartridge originally and removed it when the customer upgraded to the ZYX Ultimate Astro in late 2021. I have tried it here on our demonstrator Holbo II turntable and it sounds superb.

The Cartridge description:

Lapis lazuli Balancing Weight
An aspherical 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 the 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 a 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 amplifier through the ground line of right channel output.
You must listen to the purest sound by eliminating capacitance between 4 terminal pins.

World First C-1000 Carbon Cantilever in Moving Coil Cartridge
The ZYX Ultimate series (100, Airy, 4D, OMEGA and DYNAMIC) use a carbon cantilever for the very first time in a moving coil cartridge. The carbon rod is made from 1000 pieces of composite carbon fibre, hence the name C-1000 carbon cantilever.
This composite carbon fibre is more rigid than aluminium, iron and titanium. In addition, its specific gravity is just half that of boron. Therefore we can be sure that the C-1000 carbon cantilever is the ultimate and ideal cantilever material for analogue record playback.
The carbon cantilever gives us the widest frequency range and superior tracking performance. A further major benefit is that the mechanical sound signal picked up at the stylus can travel through to the coil in a straight and direct fashion by way of the 1000 pieces of mechanical carbon lines. This ensures that reflected, repeated or modulated mechanical sound signals are completely absent.
The overall result is that you will enjoy the finest, most natural, most dynamic and true to source sound that you have ever experienced.

Cartridge Case For REAL STEREO
The 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 occurring on the body surfaces.

Super High-speed reproduction engine
This circuit is specially processed to null magnetic resistance within the 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 lifetime 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.

Pure 6N OFC Crystal Copper Wire Generator Coils
This perfect crystal copper wire produced by a special process, in order to achieve an even sound balance across the entire audible range.
