BTW nobody uses those old and heavy headshells.
The most of us use the Orsonic , preferably the AV-101 b or s.Dear Nikola,
Where do you get these 'facts'?
I love the FR3 headshell for my FR-64s and 66s arms. Even the FR5 headshell is a fine one.
The Orsonic AV-101b I found to be the worst headshell I've heard and I quickly sold it.
For every genuine Orsonic headshell on the market......there appear to be 75 bad Chinese copies?
An FR3 headshell can be had for $180 and an FR5 ....slightly less.
Also a good match for the FR tonearms.....if one wishes to lower the effective mass......are the Yamamoto wood shells and the Ortofon 8000 wood headshell.....both of which are cheaper than the FR shells.
