Fidelity Research FR64s Headshell dilemma

I have an FR-64 and I was using an Orsonic on it to mount other cartridges after damaging my FR-7. Worked fine.

Stevenson alignment is absolutely fine not only with FR tonearms but with most of the Japanese tonearms designed for use with Stevenson by default. To make sure you can try alternative alignment methods (Baerwald or Lofgren or anything else) BUT try to detect a difference yourself before you will be affected by propaganda. Trust your ears, not some other users words. Many FR users reported that Stevenson is fine, we use FR headshell integrated cartridges this way and they are absolutely stunning (FR-7fz).

If Ikeda can’t detect it, i’m pretty sure you will not be able to detect it too. Ikeda designed this tonearm for use with Stevenson alignment and this is first thing you must try and use before you will change it.

MORE IMPORTANT:

In fact for your Denon DL-103 with its conical tip the alignment method is absolutely irrelevant! Why? Because the stylus is CONICAL. Before you will twist your cartridge in the headshell to align it with something else like Baerwald please try to understand what is conical tip and what it the result of all that tricks with alignments with this conical tip (absolutely not worth the effort) **

Fidelity-Research headshells are all different, this one (RS-141) is very nice!

Can i just ask - whilst here - do most people use a mint or a wally style protractor? I use a clearaudio very similar to Llofgren A?

The best protractor for all tonearms and turntables with all 3 alignment methods on it to choose is Dr.Feickert, there are some more expensive similar style protractors, but Feickert is "best buy".  It's very important to have PS ruler integrated on the protractor. 

People use mint if they have only one tonearm, this protractor must be made just for one tonearm. The worst solution for people with many diffetent tonearms. There is no PS ruler, too bad. 

If you see many people using the same protractor do you think it is a better protractor? I don't think so. 

Protractor with HiFi Test LP is free if Feickert is expensive. 

Not only geometry but also the arm mass is important. For this
aim you have two possibilities. The added counterweight (170g)
as well the headshell weight. To reduce  arm mass lighter
headshells as well lighter weight (than 250 g standard) can
be used. As chakster I prefer( heavy ) Orsonic AV-101 and 
lighter and cheaper Sumiko (Jelko). So there is not one
specific criterion for the headshell.
