AT-VM745xML

The AT-VMx series brings new warmth and realism to Audio-Technica’s premium dual moving magnet (MM) cartridge line, delivering an expansive soundstage that’s alive with musical detail.

Like all our MM cartridges, this updated design closely mirrors the cutter head used to make the vinyl master. It utilises two magnets, positioned to match the left and right channels in the stereo record groove for outstanding channel separation and extended frequency response. But the new VMx series also introduces material and design changes to further refine the sound, offering responsive playback that is especially sensitive to the dynamism of musical expression.

Easy to Install & Use

Each AT-VMx cartridge body has threaded inserts, enabling it to be mounted to a headshell with just two screws – no nuts required. And the redesigned stylus protector now includes a V-cut for easy reference of the stylus’s position when lowering it onto a record.

Highly Efficient Generator

The paratoroidal coil construction of the cartridge’s generator – two PCUHD coils per channel, one stacked behind the other – greatly improves electromagnetic performance, while a slight reduction in coil turns* enhances transient response for clean, lifelike sound.

*Compared to VM series cartridges.

Solid Boron Cantilever and Metal Body

The three premium VMx models (AT-VM760x, AT-VM750x, AT-VM745x) feature a solid boron cantilever. Naturally lightweight and rigid, boron transmits signals from the record groove faster than an aluminum cantilever. The result is more accurate sound reproduction that’s particularly noticeable on dynamic musical passages. The die-cast aluminum body reduces vibrations and resonance.

Interchangeable Styli

Since all AT-VMx and VM Series cartridges share the same body design and have a removable stylus, you can use almost any AT-VMNx or VMN replacement stylus* with any VMx or VM cartridge for easy experimentation with sound characteristics.
