Ortofon do a PC Triple C Head Shell Tag Wire.
I am an advocate of PC Triple C Wire used in the analogue signal path.
I like the Korf Site, much of what is done on there is quite similar to areas of interest I have in the world beyond what Korf does as a R&D.
One thing that still remained when last visited, is that a Magnesium Headshell still remains to be tested item.
I am for a long time wondering why, and have come to a view on this matter, that it is a tested material, but not with a published result, as it might have shown to be a very good choice in relation to the preferred material the site is an advocate of.
But as always 'Maybe Not'.
