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.
