    Notes: Paratrace is definitely asymmetrical above the tracing edges. #2 and #3 are both front views and they have opposite profiles, looking like front and back, but that is not the case. One is just mounted one way and the other is mounted the other way.

    Walco deserves special mention for the elaborate substrate for the teeny tiny line contact chip.

    ClearAudio Discovery: WHAT IS THAT?

    Shure V15-VMR: same as in the first post, just came out better.

    OK, these are good shots. Spectacular actually! Thank you. Wondering how they physically make those long cuts on the sides of a Shibata... How do they cut diamond this small like this? :dunno:

    What is the Digitrac I sent? I never got a good look at the tip profile.

    Very nice! Thank you! So the other Fritz Gygers I've got must be some other more traditional type of cut. The Goldring 1042 (Gyger S) certainly doesn't look like the Discovery and neither does the Goldring Eroica (Gyger II), Ortofon 540MKII (FG 70).

    Well, I can't speak for the Gyger II on the Eroica since I haven't looked at it yet. Not sure I can get it into a good enough position in my microscope to get an image of it. We'll see.

    The Gyger II does look like it! Can’t get a photo yet, though. I looked at it while holding it in my hand. It’s a little less severe looking, though.

    Rear of Aftermarket line contact:

    But this is actually the front, if you’re the groove.

    Took a shot of an Acutex 312. At first I thought it looked the same as so many of the Japanese line contacts, but then I noticed an extra cut on the rear side. Or am I seeing things?

    The STR stands for Symetrical tri radial .
    So it probably is an extra cut .

    Shibata's are the closest to that cut.

    Joseph: Uhm, extra cut? To me that would look like a typical Ogura(-Vital)-like line contact.

    Greetings from Munich!
