You can earn loyalty points on every order you place on this website. If you select to create an account at checkout, your loyalty points will be saved and you can use these to discount future orders online.
Each product page shows you how many loyalty points you can earn when you order that item. Essentially, for each £1 you spend, you earn 1 loyalty point and for every 1 point earned, 1p will be added to your loyalty point balance (this is the same as some of the UK's biggest loyalty point cards). So for example, if you spend £500, you'll earn 500 loyalty points which can be used to discount a future order by £5.00.

Description
Audio Technica VM670SP is a dedicated dual Moving Magnet Mono Cartridge for 78RPM records thanks to the large curvature radius at the stylus tip. The curvature radius is 3 mil and suitable for playing 78 RPM records from a wide variety of eras.
VM Design
VM670SP uses two magnets which are arranged in the shape of a V replicating a cutter head, instead of a single large magnet. These magnets are positioned to match the positions of the left and right channels precisely in the stereo groove walls. The result of this design is superb tracking, stunning channel separation and extended frequency response.
Mono Body
For monaural operation, left and right channels should be connected. A mono body on which left and right terminals are connected internally reduces record noise which is primarily in the vertical direction and obtains a highly focused ‘centre’ sound image compared with stereo bodies.
Magnetic Circuit
Also like the 500 and 700 series, this cartridge uses para-toroidal coils to improve the generating efficiency and to offer superb linearity, since leakage of magnetic flux in this continuous and unitised magnetic circuit is low. The use of laminated cores also helped in optimising the permeability of the cores.
Conical Bonded Stylus
A conical bonded stylus with a large curvature radius at the tip. The curvature radius is 3 mil, and suitable for playing 78 RPM records from a wide variety of eras.
The 600 Series
VM670SP has a specialised 600 series mono body with internal wiring dedicated to monaural sound. It uses the same internationally patented VM dual magnet design as the 500 and 700 series replicating a cutter head structure.
Key Features
- Conical bonded stylus with large curvature radius tip
- VM670SP uses an aluminium pipe cantilever
- Para-toroidal coils improve generating efficiency
- Mono body terminating left and right channels reduces surface noise
