Fidelity Research FR64s Headshell dilemma

@lohanimal

The factory headshell does present a dilemma - if you do not have one.
From the FR64/66 owners manual.

The distance from the front of the head shell to the stylus tip should be adjusted so that it is 7mm.

*********************************

Now a "dilemma" for me, when I owned this tonearm, was that the designer goes on to say.

A difference of 1mm more or less in this distance will not present any practical problems.

So why are you guys going to what appears to be great effort in detail for measurements, when it appears the designer himself, based on the design of this tonearm, did not think that a couple of millimetres either way, was that important ?

¯\_(ツ)_/¯

Dear chris, Back then it was not usual to mention the number of
contriburions after one's name. I can add 2007 to my user name
but the number of my contribuions is much higher . So I will not
follow your example (grin). 

As a stupid man follows talking it's obvious that the posibilities to tals more stupid " things " goes higher and higher:


"""  who cares about that Baerwald ? Who would buy those tonearms if they are not good ?

Remember Swedish SAT tonearm ?  ""

It cares the people that understand the overall alignment subject that provided Löfgren A/Baerwald solution and Löfgren B solution. As a fact the extremely expensive SAT tonearm designer choosed Löfgren A/Baerwald.

Btw, almost all tonearm buyers buy their tonearm taking in count many characteristics on its design, many but the kind of alignment choosed by the designer because almost any of them know they can use what ever they want it.

Dear @ct0517 : "" based on the design of this tonearm, did not think that a couple of millimetres either way, was that important ? ""

your whole statement posted and coming from you has no real sense because the design of any pivoted tonearm just not takes in count a comment like that.

That designer statement only confirms his very low/poor knowledge levels of the implications of 1mm-2mm differences in the overhang set up.
Yes he said it that way ( it comes in the instruction manual. ) the question is: why did it? when any pivoted tonearm can’t be designed for that 1mm difference in overhang can't makes a difference at all even with his ST choosed alignment.
Always will be a real difference that maybe we can’t detect it the quality level of what we listen of what that difference makes in tracking error and tracking distortions but are there.

Do you know which is the only difference between Löfgren A/Baerwald and Löfgren B alignments? the only difference is: around 0.5mm on the calculated overhang ( obviously that because are two different kind of alignments the null points calculated are different but with no relationship with the overhang calculated. ).

The FR designer not break the rules on the alignment issue it’s only that he just can’t understand it. His overall tonearm design has a lot of faulty/mistakes in what cartridge needs and asks to the tonearm for that cartridge can shows it at its best.

Everything is important in the cartridge/tonearm geometry alignment and its implications in the quality level we will listen with but the more important and main subject about is that we pivoted tonearm owners can understand it the true behind and the reality behind the overall tonearm alignments. This is the reall issue.

Chris, for my part I don’t care per sé about those alignment measurements I’m trying only to explain those important an critical implications.

Stylus shapes.  By way of introduction. Peter wanted to impress
his friend John with his new swimmming pool. After some time he
asked: ''and what do you think?'' John; ''well how should I put
it but is 3x3 m, not to small?'' Peter: ''you idiot the pool is 30 m.
deep!''
Now assume that you can hear , say, 14 Khz.  Assuming that
you are not from Mexico so not able to hear with you bones
what sense makes to you that your stylus can reach 40 Khz? 
Because of my age I can't hear anything above 11Khz.
I think that I can live with even conical kind which btw is in
my Magic Diamond. Reto Andreoli  the desigenr of Magic diamond
is in the busieness of cart making since his 15 year of age and 
learned the trade by Australian brothers. Nobody ever complained
about hight frequencies of this cart. To assume to know better one
should show his accomplishments not verbal capabilites.
