Audio-Technica 120E Cartridge

Dual Moving Magnet Vector-Aligned Dual Magnet design and Audio Technica's exclusive Paratoroidal signal Generator.

This unique signal generating system is composed of a unified, laminated coil core wound with a single piece of wire. Internal mechanical and electrical connections are eliminated, minimizing magnetic losses and assuring better signal transfer. The use of PCOCC wire (Pure copper by Ohno Continuous casting), a special copper with virtually no transverse crystal barriers to impede signal transmission, perfects the performance of the advanced paratoroidal coil design. Thus, the coil of the cartridge transmits distortion-free sound in which even the most subtle sonic details are reproduced with clarity and purity.

Specifications
· Output: 5.0 mV
· Cartridge Type: Moving magnet
· Stylus Type: .3 x .7 Elliptical nude round-shank stylus
· Cantilever: Alloy tube
· Frequency Response: 15Hz~25 KHz
· Tracking Force: 1-1.8

The half-inch standard mount AT-120E/T cartridge has gained a loyal following among audiophiles. It is extraordinarily crafted and provides musical enjoyment far beyond its price range. After about 100 hours of break-in, the AT-120E/T metamorphoses into a skilled artisan. You'll enjoy its cohesion, wide soundstage, tight bass and crystalline highs.

Price: $108.00 (August, 15, 2009).

Diferenças entre cápsulas MC e MM.

What's the difference between a Moving Magnet and Moving Coil Phono Cartridge? (Diferenças entre as cápsulas de magneto móvel e as de bobina móvel).

There are two types of phono cartridges, moving magnet and moving coil. The two types have different designs and performance characteristics. It all starts with the stylus or needle on the phono cartridge. The stylus travels through the grooves on the record moving horizontally and vertically, tracking the minute fluctuations in the groove that represents the music on the record. As it travels, the stylus creates a small audio signal generated by the proximity of a magnet and a coil. All phono cartridges have magnets and a coil – the difference is where they are located.

The advantages of a moving magnet cartridge are high output, which means it is compatible with any phono input on a stereo component. Many moving magnet cartridges also feature a removable and replaceable stylus. This is important in the event of breakage.

Its disadvantages are that the magnets have higher weight or mass compared to a moving coil cartridge, which means they can't move as quickly in the record groove. This inhibits its ability to track subtle changes within the groove. This is where a moving coil cartridge has performance advantages.

Moving Coil Cartridge

A moving coil cartridge is sort of the opposite of a moving magnet cartridge. Instead of magnets, two small coils are connected to the end of stylus located in the body of the cartridge. The coils are smaller than magnets and weigh much less, giving the stylus more agility when navigating the constantly changing record grooves. In general, a moving coil cartridge traces the grooves better because of its lower mass and provides more detailed and accurate sound quality.

One disadvantage of the moving coil cartridge is that it generates a smaller voltage and requires a secondary preamplifier, sometimes known as a head amp. The head amp increases the voltage enough for a phono input on a stereo component. Some moving coil cartridges have higher output and are compatible with a standard phono input, but its output will be somewhat lower than a moving magnet cartridge.

The stylus is also not user replaceable in a moving coil cartridge and must be replaced at the factory or the entire cartridge discarded if the stylus is broken.

Both types of phono cartridges will provide good performance, but if you want the best, select a moving coil cartridge.

Shure M97 XE

Shure M97XE Phono Cartridge

The M97xE is a superbly tracking, neutral, smooth-sounding magnetic cartridge, designed to provide long hours of undistorted, easy listening, without fatiguing the ear or tiring the mind.This cartridge is able to accurately reproduce very difficult musical passages, particularly in the high-frequency range, where audio modulations are the smallest and most concentrated, and stylus tip movement is consequently the most rapid. Its highly precise tracking ability and flat frequency response are made possible by Shure's unique Type II low-mass thin-wall aluminum alloy stylus cantilever, combined with a precision-crafted, finely polished, elliptical diamond tip.The very low mass M97xE cartridge shares several important features with the V15VxMR audiophile cartridge:Dynamic Stabilizer Damper/De-staticizer
· Shure's exclusive viscous-damped Dynamic Stabilizer, which maintains a uniform distance between the cartridge and the record under difficult playing conditions, such as those caused by warped records, or mismatched tonearm mass. When such stabilization is not required, the stabilizer brush can be locked up into its detent position, which, under ideal playing conditions, can provide even better sound quality.Die-cast Aluminum Mounting Block
· A die cast aluminum mounting block for secure, vibration-free attachment to the tonearm.Side-Guard Stylus Protection System
· The SIDE-GUARD stylus protection system that helps prevent stylus damage if the cartridge accidentally slides across a record. This unique feature responds to side thrusts on the stylus by withdrawing the entire stylus cantilever and tip safely into the stylus housing before the cantilever can be damaged.M97XE Technical Specifications:
· Output: 4.0mV RMS at 5 cm/sec
· Stylus:Diamond tip, Polished natural gemstone, Elliptical, Side x front radii: 0.2 x 0.7 mil
· Cantilever: Shure Type II - Very Low Mass, Heat-treated aluminum alloy / tubular, 1.0 mil wall thickness / 20 mil diameter
· Frequency Range: 20 to 22,000 Hz
· Tracking Force: 0.75-1.50g

COMPARISONSThere are many choices at or near the M97’s price, none of which are quite as sweet-sounding. The Audio-Technica 440ML, widely available for $100, offers a finer stylus and slightly better tracing ability. Grado’s Black, Green and Silver, although very good, can’t equal the Shure’s trackability and in my experience, can sound a bit brittle. Ditto the Stanton and Goldring models below $100. The Ortofon X1-MC (discounted to about $110) may equal the Shure’s neutrality, but I found it to be ultimately less satisfying. The Ortofon OM10, sale priced at $60 these days, might give the Shure a run for its money in some respects, but I didn’t have mine long enough to say for sure. Denon’s DL-110 ($140) likely shares the DL-160’s bigger-than life-presentation and incredible speed, but it can also be an acquired taste. The Benz Micro MC20E2 ($175) is a rock star, with great bass and lots of life. Finally, there’s Rega’s Elys ($225), which I found to be disappointingly flat-sounding. CONCLUSIONSThe Shure M97xE may or may not be a baby V15. I’ll leave it to those who have heard both recently to answer that. Taken on its own terms, the M97 offers way above average detail retrieval, good imaging, decent soundstaging, excellent tracking and dynamics, and terrific build quality. More importantly, and harder to adequately describe, is its remarkable listenability and marked lack of harshness. I can easily imagine someone living happily with this cartridge for a decade or more, instead of ceaselessly clamoring for something better. (There’s a word for people like that: “sane.”)I’ve stayed up late on numerous occasions with this cartridge because it ‘gets out of the way’ (as they say in the magazines) and allows the music to shine. I suspect the few affectations it exhibits are more the doing of my turntable than the cartridge itself. True, surface noise can be slightly intrusive if you’re used to moving coils or more expensive moving magnets. I also wish the Shure had slightly tighter-sounding lows on some recordings, and improved soundstaging on others. Maybe you’ll find those qualities in the V15. Then again, maybe not. One thing’s for sure: the M97xE needn’t stand in its big brother’s shadow. It’s a wonderful little cartridge that deserves an audition in nearly any sub-$1000 analog playback system.
