Actually it seems a clever contraption.
On the other hand it's ~5/600$.
I can buy 400 or more LPs for that
Follow Ups:
I'm still wondering how the external fields generated by the opposing magnets can avoid affecting the cartridge. Trying to get my head wrapped around it...
At the same time, are DIY parts readily available? It might be fun to experiment, and not just with a Linn. (A buddy has a Rega - could be adapted to that, too?)
Here's one potential source that came up in a google search:
The intensity of a magnetic field decreases based on the square of its distance from the cartridge. Therefore, it probably has very little impact on the cartridge. Furthermore, it is constant magnetic field rather than an alternating one thereby significantly minimizing its audible effect on the cartridge. For example, an alternating magnetic field from a power supply transformer will result in hum that is noticeable even at very low levels but a constant magnetic field that is very weak is basically inaudible.
Anyway, the proof-of-the-pudding is in listening. If it sounds good then the magnetic field's impact is insignificant.
Best regards,
