Dear Isanchez: It is not only that the magnesium headshell works beter because the magnesium but because the original Nagaoka ( magnesium ) has a weight of 10 grs.
Btw, those Nagaoka that you can see around ( including the one Johnny53 posted )are not made by Nagaoka, are not made of magnesium but aluminum and weights over 14grs. IMHO the one to go is for the original one ( hard to find ) and/or for the Denon one. I already try both on the XV-1 with the 505 and with other tonearms and makes a difference for the better specially on the Dyna tonearm.
Regards and enjoy the music.
