Nagaoka JT-80LB
Commemorating the 80th anniversary of the founding of NAGAOKA
The new JEWELTONE JT-80 series of MM type cartridges
This time, the cartridge housing, stylus and stylus holder have been completely redesigned to confuse the new NAGAOKA design.
The newly designed elements are Moving Magnet MM type and it is the first time for Nagoako in 40 years before the release of the "MP type" elements
The JT-80 series also won the Good Design Award 2020 a very prestigious award
The JEWELTONE JT-80 series lineup consists of two models, the JT-80LB and the top model JT-80BK are both available from stock by ALBEPRO
Regarding the bodies of JT-80BK and LB , they are different.
Although exactly the same looking , but the coil and other parts inside are different.
We cover the Nagaoka JT-80LB here
JT-80LB (Lapis Blue) new standard model from Nagaoka with an aluminum cantilever and a diamond bonded elliptical stylus. Designed to pursue performance and achieve wide range and powerful sound.
Output voltage 5.6mV
Needle pressure 1.8 gr.
Weight 6.9 grams
The new Jeweltone JT-80LB is a thing of the past on the usual medium-weight tonearms.
The powerful LB seems to us to be ideally suited for smaller turntables and systems.
The slightly rounded pronunciation, including nice lower mids, never makes voices seem too thin and gives strings a velvety foundation.
The "Lapis Blue" draws its sound images compact rather than spatial.
It has a good punch, which when combined with the clarity and bass contour provides clear and vibrant results.
