Audio Technica VM750SH Dual Moving Magnet Cartridge
The VM750SH Shibata stylus cartridge is a premier 700 Series model in Audio-Technica’s new VM cartridge line – a line that harks back to A-T’s early days as a manufacturer primarily of high-end phono cartridges, while also incorporating today’s advanced technology. Like all VM cartridges, the VM750SH is equipped with dual magnets that are positioned to match the left and right channels in the stereo record groove for outstanding channel separation and extended frequency response. The cartridge’s Shibata stylus provides greater surface contact with the record groove than an elliptical stylus does, resulting in the pickup of ultra-high frequencies with less groove stress and distortion. Includes mounting hardware.
Audio-Technica VM Technology – Closer to the Cutterhead
A cutter head carves out the record grooves. The modulations in the groove are “analog” mechanical equivalents of the original audio signals. To “read” these modulations, Audio-Technica developed the patented Dual Magnet design which duplicates the structure of the cutter head. Instead of using a single, large magnet, the two magnets are arranged in the shape of a V. The two magnets are positioned precisely to match positions of the left and right channels in the stereo groove walls. Consequently, the VM design provides outstanding channel separation, extended frequency response and superb tracking. All models feature high-purity 6N-OFC (99.9999% pure oxygen free copper) wiring for maximum sonic purity and extraordinary resolution of fine musical detail.

Para-toroidal generating system
Para-toroidal coils improve generating efficiency and offers superb linearity, since leakage of magnetic flux in this continuous and unitised magnetic circuit is low. Permeability of the cores is also optimised through the use of laminated cores.
Centre shield plate reduces crosstalk
A permalloy centre shield plate enables the effective separation of left and right channels, suppressing electrical crosstalk to below 40dB. This is similar to the actual crosstalk value found in the grooves of the record itself.
