Question on FR 66s


For some reason, search on FR 66s in agon did not turn up anything much. I recalled that recommended S2P distance is 296mm rather than 295mm and Stevenson geometry seems to work best. Is this correct? I already have FR 64s which works very nicely with Koetsu. In general, does FR 66s works well with the more modern cartridges, Lyra, Air Tight, Dynavector etc.
I am kind of curious to try it but not sure what to try it with. Beside those mentioned on my system page, I have Kiseki Blue, XV-1s and Miyajima Zero on hand currently.

Thanks for any suggestion.

Another question, is it worth buying the original FR headshell along with the tonearm, I ask this because the headshell costs about $200 and for that money there are other headshells to consider as well.
Hi Pany, You look like a philosopher: questions for the sake of questions. To many I would think. BTW nobody uses those old and heavy headshells. The price you mentioned is because they are 'original'. Whatever the merits of the 'original' may be they sell well. The most of us use the Orsonic , preferably the AV-101 b or s.
Dear Nandric, while philosophy is one of my favourite topics, the above post was not in that direction though. There is at the moment an FR64s and FR64fx on ebay and the seller is asking additional $200 for the original headshell. I am considering buying one of these hence my questions followed.
Hi Pani, I have both the FR64S and the FR64fx, and in my experience the s is much better. No matter what I did, the fx just sounded boring compared to the 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.
