Goldring new E Series Moving Magnet cartridges

Nέες κεφαλές από την Goldring και μάλιστα κινητού μαγνήτη. Είναι η σειρά Ε που απευθύνεται σε μεσαίους έως υψηλής μάζας βραχίονες, που είναι και οι περισσότεροι στην αγορά.
Οι κεφαλές αυτές έχουν τεχνολογία Magnetic Duplex που αυξάνει τον διαχωρισμό των καναλιών.

Οι συνηθισμένες κεφαλές χρησιμοποιούν έναν μαγνήτη που επιδράς σε δύο κάθετα κινούμενα πηνία για να δημιουργηθεί το σήμα από το αυλάκι του δίσκου.

Η διάταξη αυτή δεν χαρακτηρίζεται από μεγάλο διαχωρισμό καναλιών, αντίθετα η σειρά Goldring E Series χρησιμοποιεί διπλούς μαγνήτες χαμηλής μάζας οι οποίοι επιδρούν σε ένα πηνίο που είναι τοποθετημένο κατά 45 μοίρες ώστε να ακολουθεί την κεφαλή κοπής του δίσκου.


Η σειρά E έχει τα μοντέλα E1 και E2, αλλά και το E3 με ελλειπτική βελόνα.

Η κεφαλή E1 έχει βελόνα σφαιρική, στέλεχος από άνθρακα και κοστίζει 70 ευρώ.

Η κεφαλή Ε2 είναι ίδια με την E1, αλλά έχει στέλεχος από αλουμίνιο και κοστίζει 100 ευρώ.

Τέλος η καλή Ε3 στέλεχος από αλουμίνιο και ελλειπτική ακίδα, με τιμής 130 ευρώ.

They went on to explain more; “The E Series, is a range of three cartridges which are designed to deliver the accuracy of the original recording, to maintain the creative nuances, and to communicate the musicality and rhythm the artist intended the audience to hear. The Goldring E Series are optimised for the medium to high mass tonearms found on the majority of reasonably priced turntables”.

“All cartridges in the range use Magnetic Duplex Technology™, which lowers crosstalk and hence increases stereo separation. During the record mastering process the cutting lathe records stereo information as a ‘V’ shaped groove which has perpendicular side walls angled at 45 ̊. Conventional moving magnet cartridges use a single magnet that interacts with two vertically mounted coils to produce a stereo signal from the groove. This can introduce crosstalk and so only offers a modest amount of stereo separation. The Goldring E Series cartridges feature a special dual magnet arrangement. Magnetic Duplex Technology™uses two low mass magnets which interact only with their partnering pickup coil, angled at 45 ̊ to match the cutting head arrangement. This enables the cartridges to more accurately trace the record groove because they precisely emulate the geometry of the cutting head, making for better stereo separation and a more accurate, involving and musical soundstage”.

The E Series

Featuring spherical styli with a choice of cantilevers, the E1 and E2 models are intended as an improved replacement for any budget, pre-fitted or obsolete cartridge. The E3 model with its refined elliptical stylus is “a worthwhile upgrade for those wishing to squeeze even more information and detail from the record groove”.

The E1

Features a bonded, spherical (0.6 mil) stylus with a round shank. This makes the cartridge “extremely forgiving of set-up adjustment”. Also features a carbon bre reinforced ABS cantilever tube, an effective alternative to more premium aluminium or boron materials.


Approximate Retail Price £60 €70

The E2

Features the same stylus profile as the E1 but with the additional benefit of an upgraded aluminium cantilever. This 
is both stiff and light weight.


Approximate Retail Price £80 €100

The E3

Utilises the same aluminium cantilever but benefits from a superior bonded, super-elliptical (0.3 x 0.7 mil) stylus. This gives it better high frequency groove detail retrieval ability over ordinary elliptical (0.4 x 0.7 mil) or spherical (0.6 mil) styli due to its smaller front to back radius.


Approximate Retail Price £100 €130

The Goldring story began in 1906 with the manufacture of clockwork motors, springs and steel needles. This expertise was utilised in the 1920s for the production of Goldring Soundboxes, and later electro-magnetic gramophone pick-ups, and carried on into the 21st century with the release of the flagship Legacy Series moving coil phono cartridges, which are still handmade in Hertfordshire, UK.
