Can anyone suggest a good universal headshell?

Viridian, wow, a wide variety of cartridges. The Audioquest-branded Orsonic is *excellent* and might be cheaper compared to the straight Orsonic. You could try the Audio-Technica 'Technihard' series, available from Audiocubes in a few different weights. Unfortunately not universal - you will probably want to match headshell weight to cartridge weight. On the other hand, they're not super-expensive.

With the Ikeda arm, I've found the Ikeda 1S/1R headshell excellent. It allows very little twisting though and many cartridges are too long to set overhang properly. juki has 'em. So does JAT.

I have an Audioquest headshell, but I need longer screws to mount a Denon DL-103r. Does any one know what thread size they use? None of the miscellaneous mounting hardware I have lying around seems to fit.

Belyin, it will never work, and besides it is just a piece of junk, you need to sell it to me so that you can enjoy your stereo ;^)

Thom, my sincerest appologies for misspelling your name; it must get old!
