Question on FR 66s

Halcro, thanks for your information. I mounted XV-1s yesterday and there was a few more mms wiggle room than Air Tight using Baerwald geometry on Feickert protractor.
So look like it was Air Tight and not something wrong with my arm or protractor as far as I could tell.

Feickert protractor is rather difficult to see especially if I have a light source on the side or the rear to help me see better. Light source is very useful for Air Tight and Koetsu especially but not as needful for Dynavector or Lyra. Surprisingly, I get a lot of glare of the black surface. Clearaudio silver finished is easier to see but Mint mirror surface is by far the best.

I saw Uni-tractor on acoustical system website. Is that the same protractor that Dertoarm made awhile back? There is an economical version call SMARTrack. Looks interesting!

Dear Lewm: ++++ " is it a bad idea to use a "good" one? I think not. " ++++

agree. As a fact there are not bad really bad comercial protractors.

Dear Halcro: The VE calculator has not the Stevenson alignment that's the one I use to find out the correct overhang/offset angle with that 233mm StoP distance. The VE is forsing/compelling the calculations to achieve 12mm on overhang and that's why you have over 300% higher distortions over Stevenson alignment that's is the one of the three standards with higher overall distortions.

++++ " how do you decide the limit of what distortions are allowable for the rest of us....." +++++

I don't decide nothing I only post my opinion with some facts around.

Sometimes you are angry with me when I said several times that you are hearing and likes high distortions because your cartridge quality performance reviews reflect that you are hearing higher distortions than other persons. That tonearm set up confirm it as many other things and Halcro I never imagine you choosed that higher distortion set up, even that in some ways I had some kind of reason in that distortion overall subject on what you are hearing and I assume you like because is what you are hearing. Tha's all.

What you did is almost as to make a tonearm/cartridge set up at random by " feeling " and with out need of a protractor. I think we use any decent or " stupid " low price ( as Dover said. ) protractor for at least be near of a " perfect " set up in static way. We all know that on playback almost anything tend to change.

Anyway, today I learn something. I hope other gentlemans too.

Regards and enjoy the music,

Halcro - I have to agree with Raul, your numbers dont add up.

05-15-13: Halcro
The MA-505s was no problem because it's overhang is the same as the FR-66s.....however the FR-64s has an overhang of 12mm as opposed to the 15mm for the others.
So to correct for that......I reset my P to S to 233mm for the 64s.
And yes......I know that the Av and Max distortion levels go up as a result.

The FR66 should be 12mm overhang not 15. The FR64 should be 15, not 12.
If you are running 12mm overhang on your FR64 then you should be moving the arm closer to the spindle to reduce distortion, not further away.

Dear Raul,
There are dozens of posts from you extolling the advantages of Lofgren A (Baerwald) over Stevenson, and your understanding of the distortions of each geometry is obviously flawed.
It just reinforces the fact that you can never be trusted or believed?
Oh.......and do I read it correctly?.....I was right about the 15mm overhang and you were wrong?
Nothing new about that..........
