Vital Audio is a Japanese instrument cable and power supply brand established in 1991 as an original brand of Hookup, Inc., a Tokyo-based audio equipment distributor. The company was founded to address a gap in the market for cables engineered specifically for guitar tone, and their debut product, the VAII High Power Guitar Cable, became a longstanding flagship. Over the years, the lineup expanded to include the VAIII bass-focused cable (optimized for low-frequency response with 24K gold-plated plugs), the VA-Flex series of flexible patch cables, and the VA-Patch-F patch cables, as well as professional balanced (VAB-N) and microphone (VNC) cables.

Vital Audio expanded beyond cables with the POWER CARRIER line of isolated pedalboard power supplies. The series includes the VA-08 Mk-II (an eight-output fully isolated unit that became the brand's flagship power supply), the more compact VA-05 Mk-II, and the VA-R8, a rechargeable model with eight isolated outputs and USB charging. The POWER BASE VA-15 AC rounds out the range as an AC power distribution solution.

While Vital Audio is best known in Japan, their products are available internationally through retailers like Reverb and Amazon. The Japanese rock band SCANDAL collaborated with Vital Audio on a limited-edition signature instrument cable released in 2018. The brand's design philosophy prioritizes sonic characteristics tuned by ear rather than relying solely on cable specifications, with a focus on noiseless, direct sound clarity.

Vital Audio has 4 products cataloged on Equipboard, including Effects Pedal Accessories, Synth Plugins, and Instrument Cables. Their gear is featured by 16 artists, with the strongest followings in Electronic, Rock, and Pop. Notable users include yuuho kitazawa, Nick Mira, and Takahiro Yamada.
