Fidelity Research FR64s Headshell dilemma

Dear @lbelchev : A tip for your calculations and with 245mm. on EL. At recorded LP surface 80mm. position the tracking distortion Löfgren B is 0.350% and Stevenson 0.735%. Difference: 0.385% higher on ST. At 90mm. is over 0.25%

If you know what to look for those differences levels are detectable and helps too that over all the recorded LP surface the ST tracking distortions are higher too.

Of course that each one of us can take any choice we want it. What we can do is limitless and only " stopped " by our each one common sense. Now, through the time to comes " things " could change and we can take different choices to the ones we choosed today Everything is in constant movement and we can't know for sure what to expect in the audio future especially with analog/LP.

The thread turned to the monologue of one person pretending to know everything better than others, but apart from the numbers claimed to be audible distortion i want to remind that there any many other components in analog chain with higher distortion than distortion caused by cartridge alignment. And people live with it and can't detect it. 

Of course that person can head all the distortion in this world and it's a problem for him if someone can't hear it (included world famous cartridge/tonearm designers).

Modern tonearm designers comes up with new ideas and no one in the reviewers world can't detect that horrible distortion for some reason, but he knows why, the answer is "they are s.......d people". They are all have to grow up to the level of our own audiogon preacher who knows everything better. 

ViV Laboratory is another example, it's straight tonearm with underhang (not overhand). And yes, the cartridge/cantilever position is also straight in this tonearm. The don't give a F about Baerwald alignment and all reviews are positive. 

Dear chakster, I hope you are not refering to me as the person
who knows everything better(grin). 
In order to get your simpathy I want to mention to use the
same SAEC mat. In addition and by assumption that my memory
still function I think to remember that SAEC tonerams are made
by only considering the arms themselfs in particular regarding
their ''balance''. They were not interested in records and their
peculiarities. Probaly by an attempt to avoid toenearm geometry
disputes . As you can see this attempt is ignored in order to
keep those disputes alive. BTW I have chosen hedshells in which
any cart can be adjusted exactly according to their effective length. 

@nandric haha, no i didn't mean any of your posts here :) 

I remember Yamaha YSA-2 straight tonearm with no offset, here is a discussion. 

 

Dear chakster, You forget to post the picture of the ''linear carrier''
of this Yamaha invention. Should we ask all 4 owners  of
ET-2 (long) thread for explanation? Chris is my other Slavic 
brother always willing to answer any question. I assume that ET-2
is better arm otherwise there would be no such long thread about
this one.
