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.

Why not take a master tape reel to reel, played back on a well set up Studer machine (or any other decent tape player) and compare it to all the arms and cartridges combinations you think are 'right'. The one closest in performance to the master tape 'actual' recording is clearly more true and will do so on all other LP's. Hearing more out of the LP recording (piano more fuller and sustained note or more texture on strings) is then not a true sign and clearly shows that information is getting added on. This was not there in the first place on the recording.
Not many will have the capability of getting a RTR comparison, but having a good digital transfer in DSD or DXD playback could be another option for comparison.
