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.

Dear Raul, I have a few protractors mainly because I am still trying to find one that I really like. Personally, I like Mint protractor the best as far as ease of use, mirror surface and all. It is a lot easier to use for cartridges like Koetsu, Air Tight and Kiseki. However, now that I have 4 arms and most likely there will be more in the future, I don't want to keep buying new Mint protractor every time so I start looking around for universal protractor. I think Feickert is great and it has 3 geometries to choose but its finish make it harder for me to use on the 3 cartridges mentioned above. Clearaudio is fine but it has only one geometry with 4 IEC options. I figure since I spend all these moneys on cartridges and arms, why not experiment a bit more with various protractors if it may make a big enough difference in setting the arm/cartrige properly.
I am thinking of trying SMARTracker just because it seems that on the usability side, it is more well thought out that other protractors and seemed to be one that was really designed by end-user for user. It may not be more accurate than Feickert but at the very least, it would be more user friendly, I would guess.
If I can find it, I will. I actually attached the post explaining my observation to a thread where the OP was talking about the question of having to twist the cartridge in the headshell, when he was using some other vintage Japanese tonearm with Lofgren or Baerwald alignment. At that time, I was just starting to use my DV505 and was not so happy with the sound, using Baerwald (with the necessary "twist"). He claimed the twist caused no problem, but I then found that protractor on VE and re-aligned my cartridge using Stevenson. There was a big and obvious improvement in sound. As mentioned, this may be especially relevant to the Dynavector tonearms, because the vertical pivot is so close to the cartridge. I believe the vertical forces on the cantilever would be asymmetrical, if the cantilever and the vertical tonearm pivot are not aligned (another problem in vector algebra), and this may be the cause of the distortions I heard. Just a guess. I don't know whether the principle should be applied to all tonearms in general.
Dear Nandric,
ah good for you. You seem to be a rare exception :-)
Nevertheless my Arche headshells are working properly...
So which is your next tonearm project? Axiom for free or the Mexican stick?
Maybe you will have a beard until Raul will make an outing on his arm. Nevertheless we already collected so many words from him and as I just now realize he doesn't like to be defeated by anyone, so he must do something... or?
Dear Suteetat, I own 12 tonearms but use 'only' three of them. The Triplanar and the Reed 2A on my Kuzma S.R and the FR 64 s on my Sp 10. I also own some 'universal protractors' but when I got my first Mint LP I was 100%sure when I ordered the other two. Whatever the next one may be for $100 there is no contest in my opinion.

Regards,
Dear Thuchan, I am really sorry for you but Daniel obviously love me more than you. However I like to think that my ingenious comparison between 'iron horse and locomotive' (aka the usual headshell versus Arche) moved Daniel in such a way that he decided to give me a present...
You as the owner of a company are of course familiar with the so called 'intellectual ownership'. When Raul refers to 'his' pre-amp, 'his' tonearm ,etc, 'his' , he rarely mention his employee Guliermos (or similar) who is actually the technical guy behind the products mentioned.
As you know the intellectual property is of the company and not of the employees inside the company. As Raul told us himself he managed to change some fuses, caps and resistors on his own. Well I am sure that my aunt Natalija in Serbia is also capable to solder such parts with their values writen on their 'heads' in whatever component. You can observe the same capabilities in the speaker thread. Unbelievable how many speaker experts are there, capable to discovere 'cheap wire' and/ or 'capacitors' in any speaker whatever. It is like this : 'Heureka'!: cheap wire inside! No wonder Nordost get rich with such experts.
