- Cartridge-making Dictionary
 
- Audio Technica founded 17 Apr 1962
- 1962:  AT-1 moving magnet, diamond needle in uncrushed cantilever tube, higher end AT-3
- stereo AT-5
- 1966:  Moving Pulse test record
- 1967:  AT-35X, first 'VM' type dual moving magnet stereo cartridge
- AT-VM3:  first mass-production using precision moulds;
hard duralmin cantilever only 50 microns thick
- AT-VM35:  tapered cantilever
- AT-VM35F:  four-channel wideband playback over 45kHz
- 1978 AT25:  VM cartridge with toroidal power system
- 1979 AT120E/G:  low-loss paratoroidal power system with a magnetic shield
between channels, each with Omega (broken circle) toroidal coils in parallel
- 1986:  AT=ML150/OCC low oxygen long crystal copper wiring
- AT33E
- 1987:  AT33ML using single-crystal high-purity oxygen-free copper
- 1997:  AT150MLX
- 2011:  AT150ANV sapphire cantilever
- AT-VM95 vs AT95E:  VM95 has greater frequency response and higher output,
threaded mounting inserts
- AT-VM vs AT-VM95:  VM uses paratoroidal coil construction
(two coils per channel - one stacked behind the other) with OFC wire
- VM500 vs VM700:  700 has die-cast aluminum-alloy housing and tapered cantilever;
all use 99.9999% pure oxygen free copper wiring
T4P REFERENCE SERIES VL
SKU:  LPGATSER05L
T4P Reference Series VL phono cartridge for reference quality discernment and core competency in a P-mount phono cartridge.
The T4P Reference Series VL offers very high accuracy and musicality. Its Vivid-Line diamond is exquisitely polished with precision and then carefully mounted on a thin metal alloy tubular cantilever for long playing life and exceptional tracing of record grooves.
The result is a world-class performer and one of the finest P-mount cartridge crafted today,
with exceptional fidelity to original recordings.

CARBON FIDELITY CFT4PSE cartridge
Code:  CFT4PSE
Carbon fiber technology for remarkable nuance and tonal complexity
Harmonically exquisite, refractive, large multidimensional soundstage
Super Carbon Fiber cantilever for excellent tactile acuity to grooves
Spectra Elliptical diamond for very fine tracing accuracy
Diamond tip r/R radii: 8 x 18 µm (.0003 x .0007 inch)
Developed and manufactured in Japan
Carbon fiber composites offer 10 times the strength of steel at half the weight. Co-developed and designed with LP GEAR by Audio-Technica's best engineers, new Carbon Fidelity T4PSE Spectra Elliptical (CFT4PSE) cartridge benefits from the latest quality parts and materials technology featuring a super carbon fiber cantilever that respond to the most complex high amplitude attacks and transients as well as the most heavily recorded passages. The updated design, tight specifications, Twin-Flux™ magnets, high-quality moving system fulcrum and radial damping ring allied with a Spectra elliptical diamond tip produce music that makes you want to listen.
Mastered to illuminate in comparison to lofty cartridges beyond the economics of most listeners, the CFT4PSE touches and endears the more you listen. You won't want to go back to your underperforming or pricey cartridge. You'll hear, feel and sense the music exquisitely rendered - harmonically full-bodied, refractive and refreshingly crystal clean with luminous detail spatially radiating with realness. You'll experience remarkable note clarity, projection and nuanced tonal complexity previously unheard and unappreciated.

Footnote:  Carbon fiber composites offer 10 times the strength of steel at half the weight. Each producer's carbon fiber differs from those of its competitors, and the processing details are considered to be intellectual property.  The special carbon fiber used in the Carbon Fidelity cartridges and styli is patiently and expertly considered for its signature characteristics to bring out the subtleties and finesse of music extracted from the grooves of records and LPs.
For carbon fiber info see: "The making of carbon fiber".
