Nagaoka

Nagaoka claims to currently handle around 90 % of the world’s processing of stylus diamonds, taking a leading role in this highly specialized field.

In the first decades after its founding, Nagaoka focused primarily on precision jewelry manufacturing. Today, the company takes pride in its microfabrication technology, which sets international standards for working with hard-to-process materials such as diamond, carbide, and ceramic.

An impression of the “Japanese spirit” and manufacturing culture can be seen in the following video:


MrStylus

MrStylus has been offering NAGAOKA products from the very beginning and highly values both the technical and sonic quality of their cartridges and styli.

With the switch to a selective dealer distribution model, we are pleased to continue offering a comprehensive range of Nagaoka cartridges, styli, and headshells.

On NAGAOKA’s 80th anniversary, the company presented a special gift not only to itself but also to analog enthusiasts: the JEWELTON JT-80 cartridge. Visually, the system already appears significantly more modern than many of the manufacturer’s previous models.

Test listening is now available in Augsburg / Inningen.


The system’s performance in the listening test is described in STEREO issue 3/2021 (excerpt, translated):

Nagaoka JT-80LB
The small “Jeweltone” MM plays confidently and straightforwardly. Due to its pronounced lower registers, it delivers – within reason – an extra portion of punch and also works well in more affordable systems thanks to its relatively high output voltage. SOUND LEVEL 60% | VALUE FOR MONEY ★ ★ ★ ★ EXCELLENT

Nagaoka JT-80BK
With its top “Jeweltone”, Nagaoka really outperforms expectations! What this MM offers in terms of naturalness is unmatched in this class. The playback is further distinguished by its detail richness and a solid, unaffected character. SOUND LEVEL 77% | VALUE FOR MONEY ★ ★ ★ ★ ★ OUTSTANDING
