Set the tone of your listening experience with Audiocadabra™ custom handcrafted SuperClear™ Cords and SuperQuiet™ cables! We are delighted to present the Audiocadabra Ultimus4 Solid-Silver SuperQuiet Data-Only USB Cables, our 4th-Gen Hi-Speed USB cables, that are crafted with carefully selected 106% IACS pure solid-silver 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 4th-gen Audiocadabra cables is to minimize coloration and optimize performance using wire geometries that maximizes EMI immunity, premium custom materials that enhances performance and designs that enables meticulous craftsmanship. All of these improvements makes our custom handcrafted cables extremely quiet, effortlessly clear and tonally delightful.

Our design goal for the Audiocadabra Ultimus4 Solid-Silver SuperQuiet Data-Only USB Cables was to create a cable that out beat our former best-selling Audiocadabra Ultimus3 Plus Dual-Headed Solid-Silver USB Cable (This 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.

The SuperQuiet ‘Data Only’ USB cable, like its predecessor the Dual-Headed USB cable, is split into two sections—one section carrying only data and the other dedicated to carrying power. The data and power lines are physically placed away from each other, design further improved by double braid-shielding, massively reducing the problem of radiated power supply noise that typical USB cables are prone to by design. Special Edition ‘Data Only’ version with 5v wire removed is now optional and works only with select USB DACs that accommodate this type of architecture.

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 Ultimus4 Solid-Silver SuperQuiet Data-Only USB Cables employ advanced wire geometries with double braid-shielding technology for EMI and RFI immunity, superior dampening mechanism to reduce mechanical vibrations and apt grounding strategies used ensures one of the lowest noise floor of any USB audio cables, regardless of price, resulting in a velvet black background to the music.
