One of the most important aspects of Record Player cartridge design is the diamond tip of the stylus.
It is this jewel which has to retrieve information often represented by variations that measure millionths of an inch.
If the profile of this diamond is cut to the wrong shape it will damage records and reduce the amount of retrievable information.
The moving coil Shiraz cartridge has a stylus which we believe is the world's best diamond profile design.
The Swiss made Gyger II has a super fine line profile offering excellent tracking ability with stunning detail retrieval and low surface noise.
The body is made from solid aluminium alloy and fitted with a robust broadcast standard generator uniquely fixed to the body with three spikes giving it precise alignment and coupling without using distortion inducing adhesives. Excessive cantilever movements at certain frequencies are damped by the capacitors mounted directly to the generator over the coil where they accurately preserve the minute signal. The Shiraz produces relatively high output for a moving coil design, which is important for a good signal to noise ratio and channel separation, but requires careful matching to preamplifier phono stage.
Roksan have employed complex engineering techniques in the Shiraz cartridge in order to extract the most information from the groove of your records whilst never damaging the groove itself.
There are several main areas where the Shiraz distinguishes itself from other cartridges:
Astonishing level of detail.
Ease of tracking highly modulated grooves.
Uncompressed dynamic range.
Flat frequency response to beyond 30 kHz allowing harmonics to be naturally reproduced.
These qualities are directly related to sound mechanical and electrical engineering principles.
The Shiraz utilises a broadcast standard moving coil generator rigidly mounted, with 3 spikes, into a solid machined aluminium alloy body.
The Shiraz is fitted with a super fine line stylus profile.
The Shiraz is critically damped balanced cartridge, with ultra low noise surface mount capacitors fitted directly next to the generator's coils.
The Shiraz cartridge is particularly sensitive to precise alignment. The fine line stylus requires fine Vertical Tracking Angle adjustment.
