Aftermarket High Quality Replacement Stylus (Copy / Pattern / Replica Non CEC )
A worn stylus can cause serious ( Irreversible Damage ) to your records, and provide poor sound quality
Replacement Stylus ONLY - Cartridge Shown NOT Supplied
We recommend that you purchase at least two replacement styli ( Spare ) especially if you are buying for an older cartridge. Manufacturers have been phasing out many replacement styli for decades & so the next time you need one a spare for your older cartridge you may not be able to find it. & many 100s of suppliers of Cartridges & Turntables have ceased production or went out business .
Genuine Stylus - Original as fitted by Cartridge OEM
Copy/Pattern/Replica - If no longer in production Aftermarket Replacement
a. Nude Diamond.- Best & Most Expensive Option
The stylus is a whole diamond, specially shaped and glued or fastened to the cantilever.
b. Tipped diamond - Least Expensive option
. Here, a stylus tip of diamond is mounted on a metal shank.It is usually made of diamond the hardest material known - to give it maximum durability. However, the fact that it is of diamond is not sufficient in itself, for its construction and shape are also crucial factors in sound quality. Many less inexpensive Hi-Fi cartridges use a so-called “tipped” diamond, where the diamond tip is mounted on a metal shank. However, such a shank may increase the stylus tip mass and thus impair the cartridge’s transient reproduction, in comparison with a cartridge that uses a nude untipped diamond.
The SPHERICAL ( Conical ) Stylus
The spherical shaped stylus is the simplest and cheapest to produce and it is, therefore, the most common. Spherical styli can be recommended in all cases where robustness and economy are taken into consideration in the purchase of a cartridge.
The ELLPITICAL stylus
The elliptical shaped stylus bears greater resemblance to the triangular shaped cutting stylus that is used when cutting master records.The elliptical stylus is able to follow the groove oscillations more accurately than the spherical type, and its distortion and phase error will,therefore, be less.
Advanced Stylus Profiles
The HYPER ELLPITICAL stylus
Hyper-Elliptical is an extreme elliptical tip.which are precision ground and are actually often closer to Contact Line than most ellipticals.
The SHIBATA stylus
Various cartridge manufacturers have been inspired by the Shibata shape and now produce cartridges with stylus shapes that give the same advantages as the Shibata. quadraphonic systems never really caught on with consumers, but they have helped to speed up the development of stylus types that improve playback of stereo records in the form of a more precise treble reproduction, lower distortion, and less record wear.
Other Advanced Profiles & Trademarks include
BI-ELLIPTICAL , PRAMANIC , QUADRAHEDRAL , HYPERBOLIC , PATHEMAX , FINE LINE , LINE CONTACT , MICRORIDGE MICROLINE PARATRACE , REPLICANT , FG , VDH , SUPER FINE LINE
Advanced Stylus Profiles as used on Hiend Cartridges offer much improved Sound Quality , Extended Stylus Life , Extended HF Response & Tracking almost exactly duplicates the shape of the cutting stylus used to produce the original master disc from which records are made. This enables it to track portions of the groove other styli simply cannot reach. The result is extremely accurate tracking of high-frequency passages and ruler-flat frequency response within the audible range
Due to Stylus Shape & Profile advanced stylus make greater contact with the record groove wall for better sound quality
The cantilever of a record cartridge, like the stylus itself, is an important part of the vibration system and necessary in order to faithfully transmit the vibrations from the record to the Stylus.
A variety of materials such as Aluminum,& Expensive cartridges use Sapphire, Beryllium and Boron are used to make cantilevers of different shapes and dimensions. The lighter and stiffer the material, the better and more accurately the cantilever can transmit vibration.
In today’s high-end cartridges, precision is also required for the materials, processing, and assembly of magnetic circuit parts as well as the suspension mechanism connected to the cantilever.
Notes on Mono Records & Cartridges Styli
Modern Microgroove Records have a V profile Groove & Modern Mono Microgroove Re-issues
0.7mil is Suitable for Reissue Monaural LP and a Mono LP of after 1960.
1.0mil is Suitable for the Monaural LP of a deep groove of the first press of the 1950s.
However, both styli can trace the monaural LP of all generations without a problem.
When you listen to the monaural LP of all generations, we recommend 0.7mil.
When you listen to a monaural LP of the first press of the 1950s mainly, we recommend 1.0mil.
Why Mono ?
A mono cartridge is mechanically different from a stereo cartridge. Simply switching a stereo cartridge to mono does not work perfectly. Despite what manufactures claim mono switches invariably add the two channels by simply shorting the two channels together, even very" expensive units do this. Hiend units can sum the two channels with extra electronics to eliminates the vertical response and improve the signal to noise by 3dB. However even summing does not provide the ultimate, a cartridge designed for mono, with a single coil and no vertical movement reduces surface noise, vertical noise and fits the groove properly.
Older Mono records have a U type Groove Mono/78RPM 3.0mil is the accepted norm & Steel Needles for gramophone records
other types used by collectors are 2.0/2.5/3.0/3.5/4.0/8.0 ( MIL = 1/1000th of a inch )
2.0MIL - 2.0 X 0.4 mil Elliptical diamond - worn LPs, some transcriptions.
2.5MIL - 2.5 X 0.5 mil elliptical diamond - late unworn 78s
3.0MIL - 3.0 X 0.5 mil elliptical diamond - most 1905 to 1940's, slightly worn 78s & transcriptions, & some Edison discs.
3.5MIL 3.5 X 0.8 mil elliptical diamond - old or worn 78s, transcriptions.
4.0MIL 4.0 X 1.0 mil elliptical diamond - Edison Diamond & very old/worn discs, raw aluminium, RCA home recordings., also Pathé vertical discs
8.0MIL 8.0 mil conical sapphire - RCA home recordings, and worn Pathé vertical discs.
