    Nothing really new - Goldmund did it more than 30 years ago, as far as I remember using steel and a special high-speed metal point.

    Probably the Godmund patent expired and anyone can manufacture devices working on this principle now.

    I think Mod Squad Tiptoes were sold on the same concept, weren't they?

    No such thing exists in the context of wave propagation in solid media. The term is most commonly associated with one-way energy transfer in gear assemblies or torque converters. Just try measuring the output of an accelerometer on the top side of a cone subject to vibration at the pointed end.

    It is now audiophile jargon - once a designation has been used for more than thirty years it is considered adopted!

    Agreed. Just one example in this hobby where arm waving substitutes for scientific fact.

    The Jadis JD1 and Theta Drives adopted this principle as well.

    It's not a principle. It's lore.

    Yes Ron, you are correct, it was Mod Squard with their Tiptoes, later it was Pin Points out of the Nederlands, Gryphon used in on their first preamplifier in the eighties, YBA, Goldmund and many others used them too. Nobody has a patent on the idea and today there are many versions of them, generally all called spikes and has become a almost mandatory tweak for most.

    The idea may have its roots in the symbol used for drawing diodes in electrical schematics.
    The only time I've ever found spikes to be useful is in preventing speakers and equipment racks from putting flat spots in carpet. They improve the sound by reducing the level of disapproval from the spousal unit.
