Ikeda IT-407 tonearm geometry
I’ve read all there is to read on this subject and never got satisfaction. It inspired me to ask this question earlier.
“Cartridge alignment with non slotted headshells”.
The main reason I have a problem with these headshells is with my Ikeda it407 (chrome) tonearm, the cartridge must be twisted quite a bit in towards centre. I have a vintage audio technica headshell with fixed holes and I don't even need a protractor to see that it won’t work. I don’t think stevenson alignment is this bad? I don't have a protractor with stevenson. My pivot to spindle distance is set perfect using my smartractor. I’m quite sure it is not possible to use an spu headshell in my Ikeda with the tonearm at the recommended distance without being seriously out of alignment. I’ve researched this online and I’ve spoken to Bill Demars at Beauty of Sound. He said that the recommended pivot to spindle distance is probably wrong and some people position at a further distance. He agreed about spu in spu headshell in the ikeda arm not being ideal. I’ve never heard if anyone has asked Ikeda these questions about their arm.
I do really like this arm, the way it sounds and the fact that is has a removable headshell,
I’d just like to have better understanding of it?

I recommended Dr.Feickert because you said this: I don’t have a protractor with stevenson. Believe it of not, but i don’t like mirror under cartridges, i have very bad experience with Van Den Hul mirror protractor, i prefer white lines on black surface (just like Feickert, better for my eyes) and it’s enough for me to align cantilever with these lines. Additional light is a good bonus for Feickert. A good vision is also good bonus, i can handle it. You can always order Stevenson protractor for one particular tonearm. If you don’t need Stevenson alignment at all it’s another story, but then you will have to twist your cartridges in the headshells on Ikeda. |
I thought I would try Stevenson but I keep hearing how poor it is. Maybe uni-din is a better choice. Check this out. https://www.analogplanet.com/content/uni-din-versus-löfgren-b-just-clarify @ |
