Set the tone of your listening experience with Audiocadabra™ custom handcrafted audio cables and accessories! We are delighted to present the Audiocadabra Ultimus4 Solid-Silver Power-Isolated USB Cables, our 4th-Gen Hi-Speed USB cables, that are crafted with carefully selected 99.99% pure solid-silver conductors individually sheathed in Teflon dielectric, double braid-shielded and terminated with premium-quality USB plugs.

Every audio cable is a balance between performance and penalties—this balance is determined by wire geometry, mechanical construction and material science. Our pursuit with the 4th-gen Audiocadabra cables is to optimize performance using wire geometries, materials and designs that maximizes EMI immunity and that is just one of many things we do to make this generation of cables extremely quiet compared to our previous generation of cables.

Our design goal for the Audiocadabra Ultimus4 Solid-Silver Power-Isolated 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 Power-Isolated USB cable, like its predecessor the Dual-Headed USB cable, is split into two sections—one half carrying only data and the other dedicated to carrying power. The data and power lines are physically moved 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.

The advanced double braid-shielding technology and grounding strategy used in the Audiocadabra Ultimus4 USB cables ensures one of the lowest noise floor of any USB cables on the market resulting in a velvet black background to the music.
