Interesting how in investigations undertaken of Headshells in the past years where Wonder Materials were being introduced as the must have design.
When the comparisons to other more traditional materials were being showed, Magnesium Headshells have not been included in a Comparison ????
A 9 gram Magnesium Headshell has been my choice for multiple years. I own a large batch of 9-10g Types.
I have not felt the need to return to older used options, or seek out Wonder Headshells.
As for the Link I've seen MS 9 - MS 10 - MS 11 sell for close to £100 in the UK as a single item. There are come very greedy types in audio, this will keep one out their path.
