Goldring E4 Moving Magnet Cartridge Goldring introduces its flagship E Series moving magnet cartridge: E4. Designed as the ultimate upgrade for any modern budget or midrange turntable, E4 represents the pinnacle of E Series engineering and performance. E4 is designed to be compatible with all medium-to-high-mass tonearms of the type found on the majority of budget to midrange turntables. And because it’s constructed using the same high-quality core as the other E Series cartridges in the range, E4 is ideal both for those who wish to upgrade an obsolete cartridge in its entirety or those who want to boost the performance of their existing E Series cartridge by replacing the stylus Key features at a glance:New super-elliptical nude diamond stylus features lower effective tip mass, improved rigidity and better high frequency detail retrieval than ‘bonded’ elliptical alternatives.The lightweight and superior stiffness of the hollow aluminium cantilever allows the stylus to trace medium-to-high frequencies with greater accuracy.Magnetic Duplex Technology™ allows a more accurate transcription of the stereo groove which results in a more accurate soundstageExpert adjustment facility: Unlike most designs, E4 allows micro-adjustments to be made during the production process, ensuring each cartridge leaves the Goldring factory with optimised channel balance and crosstalk settingsNew super-elliptical nude diamond stylusThe E4 features a ‘nude’ super-elliptical stylus of just 7.6 x 18 microns (0.3 x 0.7 mil), cut and polished from a single homogeneous piece of diamond. This makes for a lower effective tip mass of improved rigidity, which in turn means its ability to retrieve high-frequency detail is dramatically improved when compared to the ‘bonded’ elliptical stylus alternative. It’s far less likely to ‘mis-track’ or overshoot when tracing high-frequency groove modulations, and because of its finely polished 7.6-micron profile it can more effectively fit into closely packed inner grooves. Lower distortion, improved transient response and a flat frequency response all contribute to superior fidelity when compared to any price-comparable alternative. Hollow aluminium cantileverTo complement its low tip-mass stylus, the E4 features a hollow aluminium cantilever tube. The light weight and superior stiffness of the material allows the stylus to trace medium-to- high frequencies with greater accuracy, while simultaneously reducing distortion and mis-tracking. Magnetic Duplex Technology™Stereo information is contained in a single ‘V’-shaped groove that has perpendicular sidewalls angled at 45 degrees. Conventional cartridges, which use a single large magnet interacting with two vertically mounted coils (one for left-channel information, one for right) to extract a stereo signal from the groove, can permit high levels of crosstalk - and consequently only a modest amount of left- and right-channel separation. E4 uses Goldring’s Magnetic Duplex Technology™ that positions two low-mass magnets at the same angles as the coils - so each magnet interacts only with its partnering coil. This allows the E4 to transcribe the information in the groove more accurately, and results in greater stereo separation and a more accurate soundstage. Expert adjustment facility‘Azimuth’ describes the angle that the vertical centre line of the stylus makes with the record’s surface - it must be exactly perpendicular to the groove. Owners of budget and midrange turntables usually have no facility to adjust the azimuth, so it’s vital the cartridge has been precisely adjusted before it’s fitted to the turntable’s tonearm - badly adjusted azimuth can cause increased crosstalk and uneven channel balance. E4 is designed to allow micro-adjustments to be made during the production process, ensuring each cartridge leaves the Goldring factory needing no further azimuth adjustment.
