Pairs well with
The AT-VM670xSP cartridge is designed for playing 78 RPM monaural records. The dual magnets in this cartridge are internally connected to reduce record noise and obtain a highly focused “center” sound image that stereo cartridges can’t provide.
Audio Technica AT-VM670xSP 78RPM Moving Magnet Cartridge
Like all VMx cartridges, the AT-VM670xSP features PCUHD® (Pure Copper Ultra High Drawability), resulting in richer, more nuanced audio reproduction. The number of coil turns has also been slightly reduced to improve transient response, allowing the cartridge to react more quickly to signal changes for stunningly clean music with lifelike immediacy. The stylus’s 3.0 mil curvature radius makes it an excellent choice for playing 78s from many different eras.
We’ve also added threaded inserts to the die-cast aluminum body of each VMx cartridge, making it easier to mount (just two screws required), especially to the integrated tonearms common on high-end turntables. And a new V-cut in the stylus’s flip-up protector provides quick reference of the stylus position, serving as a guide when lowering the stylus onto a record.
All VMx cartridges feature a generator with paratoroidal coil construction: two coils per channel – one stacked behind the other – for greatly improved efficiency. A center shield plate separates the left and right channels to reduce crosstalk and maintain a clear stereo image. The copper wire used for the coils has been upgraded to PCUHD® (Pure Copper Ultra High Drawability), resulting in richer, more nuanced audio reproduction. The number of coil turns has also been slightly reduced to improve transient response, allowing the cartridge to react more quickly to signal changes for stunningly clean music with lifelike immediacy.
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.
INTERCHANGEABLE STYLII
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.
