Functionally the same as a progressive spring. Within the tiny range of motion playing music it is probably pretty linear and with freedom of motion in all planes should be about as good as any other spring. The drawback with all springs is they are resonant, and these will be too. So they will probably need to be tuned with weight just like springs. Bottom line you would have to compare but I would suspect they are maybe a little better than Nobsound springs for only about seven times the cost.

What do we think of these isolation devices, manufactured by Michell - of 60s/70s Transcriptors/A Clockwork Orange fame - and others?
Michell designed them for un-sprung turntables like the Transcriptors. Two powerful magnets of washer form are arranged to repel each other, the upper one placed to slide on a vertical pillar.
They are nicely manufactured and presented and reasonably priced at £210 for a set of three (conforming to the old Linn triangular support mantra). Some of the competitor examples are a bit cheaper.
I have not heard systems using them. Has anyone?
How do they perform under CD players, amplifiers, DACS and other electronic components?
