Episode 17 of The Earworm Podcast goes straight to one of the most overlooked links in the entire audio chain: the cable. Bryan Clark and Patrick Cloud sit down with Dariush Rad, owner of Asterope, to explore why musicians will spend thousands on guitars, microphones, pedals, preamps, and converters; then connect it all with a cable they barely think about. Dariush breaks down signal-to-noise ratio, shielding, directionality, conductor geometry, and material quality, explaining how every connection can either preserve or compromise the original signal. The conversation challenges the idea that “a cable is just a cable” and asks a bigger question: how much of the sound we’re constantly trying to fix downstream was lost before it ever got there?
Dariush also shares the unlikely story behind Asterope, including his journey from music into aerospace technology and how lessons learned developing high-performance, low-voltage avionics helped reshape his approach to audio. From copper purity and dielectric materials to Asterope’s 98% cross-braided shielding, non-metallic barrels, solid-core connectors, and lead-free silver solder, the episode gets deep into the engineering behind preserving signal integrity. It’s part audio science, part aerospace engineering, and part reminder that sometimes the biggest improvement to your tone isn’t another piece of gear. It’s making sure the sound you already have actually makes it to the other end of the cable.
