Goldring E4 Phono Cartridge

Description

Goldring E4

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 aluminum 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 soundstage

• Expert
  adjustment facility: Unlike most designs, E4 allows micro-adjustments
  to be made during the production process, ensuring each cartridge leaves
  the Goldring factory with optimized channel balance and crosstalk settings

New super-elliptical nude diamond stylus

The 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 aluminum cantilever

To complement its low tip-mass stylus, the E4 features a
hollow aluminum 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 center 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.
