Hapa Audio Aero AG Digital Cable

The Aero AG Digital brings Hapa Audio's silver-conductor aerogel platform to S/PDIF coaxial connections: a nano-polished UPOCC silver conductor in an aerogel dielectric, built to a 75-ohm impedance.

Silver and aerogel, for the coaxial digital link.

The Design

Hapa Audio is a small cable maker in Aurora, Colorado, founded by Jason Wong in 2020, and every cable is built by hand. Hapa's Aero, Haiku, and Torsion cables suspend the conductor in aerogel, a silica material that Hapa describes as 99.8% air, in place of conventional plastic insulation. Hapa says it pioneered aerogel dielectrics in cables and polishes each conductor by hand before it goes in. UPOCC stands for ultra-pure Ohno continuous cast.

S/PDIF is a 75-ohm interface. The AECO BNC termination is a true 75-ohm connector, so it keeps the cable's impedance consistent through the connection, and an ETI Silverlink RCA termination is available for components with RCA digital inputs.

How It Sounds

Listeners who have heard Hapa's silver aerogel cables, including AudioCircle's Haiku tour reviewers, describe a stage with notable space. We'll add our own listening notes for this cable as we gather them.

Where It Fits

Use it between a transport, streamer, or digital converter and your DAC. The Aero Cu Coax is the copper version. Tweek Geek offers in-home auditions nationwide.
