Set the tone of your listening experience with Audiocadabra™ custom handcrafted SuperClear™ Cords and SuperQuiet™ cables! We are delighted to present the Audiocadabra Optimus Solid-Copper SuperQuiet USB Cables, our new-gen Hi-Speed USB cables, that are crafted with carefully selected 101% IACS pure solid-copper conductors individually sheathed in Teflon dielectric, double braid-shielded and terminated with custom copper-alloy USB plugs.

We believe that there is no such thing as a ‘neutral sounding cable’; every audio cable is a balance between performance and penalties—this balance is determined by wire geometry, material science and mechanical construction. Our pursuit with the new-gen Audiocadabra cables is to minimize coloration and optimize performance by using wire geometries that maximizes EMI and RFI immunity, sourcing premium custom materials that enhances performance and incorporating proven extreme designs that also enables meticulous craftsmanship. All of these improvements ultimately makes our custom handcrafted cables extremely quiet, effortlessly clear and tonally delightful.

Our design goal for the Audiocadabra Solid-Copper SuperQuiet USB Cables was to create a cable that out beat our former best-selling Audiocadabra Ultimus4 Solid-Silver SuperQuiet Dual USB Cables and Ultimus3 Plus Dual-Headed Solid-Silver USB Cables (The latter cable was reviewed at 6moons by Marja & Henk. Read the complete review here—LINK.) with a lower noise floor and a much delightful tone. All of these new-gen sonic improvements at the old-gen cable pricing.

In order to set a benchmark performance, all materials used in our products are meticulously manufactured to specifications and are available exclusively from us. The Audiocadabra Optimus Solid-Copper SuperQuiet USB Cables employ advanced wire geometries with double braid-shielding technology for EMI and RFI immunity, superior dampening mechanism, custom materials, apt grounding and construction techniques used ensures one of the lowest noise floor of any USB cables, regardless of price, resulting in a velvet black background to the music. Designed to delight both studiophiles and audiophiles alike.
