"I’m impressed. Your DiD’s are imparting a clarity, transparency, and liquidity, that is luscious, my friend.
No major review is required here. These are the real thing! And very easy to use."

    The DiD devices utilize dissimilar materials to dissipate resonance and are coupled with bearings to also isolate the electronic component from vibration. Precision made of highly polished billet Aluminum, solid Cherry and Brass with steel bearings.
    Our DiD-SPK are designed for speakers, larger and with no bearings these help define the lower frequency range and improve the soundstage.
    We now make Stainless Steel spikes with Brass lock nuts for speakers. These are massive and the density and differing materials provide a solid foundation with improved clarity.
