They produce both moving magnet and moving coil cartridges and have supplied product to other renowned audio companies throughout the world: such as Townshend Elite, Garrott Brothers, Goldring and Hana as well as many other well known Japanese and European companies. ES-70EX4 is their premier moving magnet cartridge and a genuine masterpiece. Notably, Garrott Brothers adopted it as a basis for their prestigious and acclaimed P77i and Optim S2 cartridges. Stylus is state-of-art: utilising SHIBATA grain oriented nude diamond, with a cantilever and suspension of equivalent refinement. Combined with a patented magnetic circuit, the cartridge achieves stunning quality of sound and imaging (soundstage replication) to realize a sense of outstanding naturalism and emotion from vinyl records. Being both medium compliance (20 cu) and weight (5.0 g) it will match well with any good quality tonearm, vintage or modern, of medium effective mass (8 -14 grams). However, for whatever reason, the EX-70EX4 is intrinsically an exceptionally stable tracker and should prove to be amazingly tolerant of any competent arm with which it is partnered. Of the many high performance moving magnet cartridges Ive owned, the ES-70EX4 is genuinely in my three top favourites and a really superb all-round performer. My other favourites are Signet TK-9Lca and Shure V15 V-MR (and Ive owned some very accomplished and very expensive alternatives).
