Fidelity Research FR64s Headshell dilemma
SAEC was superior brand. They were used by Micro Seiki, Technics, Victor as upgrade of stock tonearms.After CD they have just ceased production of tonearms. 
Fidelity Research FR64s Headshell dilemma
I do remember as story of SAEC then the first series was so condemned by alignment geometry specialists that they have changed into more normal one after 308 series. It's obvious that next series was more geometrical :) So Japanese know about geom... 
Fidelity Research FR64s Headshell dilemma
Lewm, tonearm isn't a geometrical object it's also a mechanical one.Yes Logfren and Baeward relied on geometry as we do build models of real world - it's part of science. After making model we do measurement in real life if results are as predicte... 
Fidelity Research FR64s Headshell dilemma
Yes lewm measurement is a key. In the modelling then geometry was used to measure land in ancient Egypt results was easier predictable. Tonearm is much more complex.To order such LP with 1 kHz tone is not big problem these days and even it's not e...

Nandric, show me measurements not geometry assumptions. I don't neglect models.I am not believer in Stevenson or Baerwald superiority.  
Fidelity Research FR64s Headshell dilemma
If we do speak about scientific arguments we have to use science principles.I can see hypothesis - geometry. A lot of very exact calculations from derived data. Although I was thought in the university that after hypothesis you have to do experime... 
Fidelity Research FR64s Headshell dilemma
If to look into details you'll find that  the world isn't perfectly round. But devil is always in the details. But better to believe in round globe. Although of course 0,001 mm is very important as feeling of mindfulness can be lost. 16.863 or 1... 
Equal or better tonearm than Jelco for like amount of money
lewm yes it my lapsus linguae.

Chakster I do have 750EB and with heavy (not original) headshell it’s in the region of 20 with test disk.Although Jelco abandoned old series and new series compliance is much higher. In 12 inch they do have only 13 grams. https://www.jelco-ichika...

Chakster TS-350S MKll  effective mass is ~ 9 grams 
Equal or better tonearm than Jelco for like amount of money
Groovemaster more less  targeted for low compliance designsNew Jelco series was more for modern medium or high compliance designs. Actually there is no substitution of current production with removable headshell.  
Jelco tonearms closes
If to count into the list Jelco OEM business like current Ortofon tonearms a lot of ideas can be lost forever. 
Ikeda 9 Cartridge Squeaking
Nandric, these particles sits quite tight on magnet, I so they are magnetic ones. Cartridge works like magnetic filter of dust or debris. As Ikeda magnets sits even closer to dust (surface) it filters more material.It can be seen in electromagneti... 
THE GOLDEN AGE OF TURNTABLES!
Tulipmania in these days are wiring prices. It's a golden age for cableman.A lot of technologies in cartridges are lost especially in MM and MI. The only bright side is return of Technics. 
Ikeda 9 Cartridge Squeaking
Ikeda 9 cantileverless tracks 90 um. At least EM and CV, personal experience.The biggest problem is debris especially magnetic which clogs suspension magnetic gap etc. First one which I have got had good diamond but suspension was so clogged that ...
