Not for: Anyone whose devices only have an optical port or HDMI ARC/eARC.
What the AI looks for in Digital Coaxial Cables
- Impedance
- Use cable specified as 75 ohm. S/PDIF coax is a 75-ohm interface. A mismatch can cause dropouts on longer runs.
- Connector fit
- RCA plugs should grip firmly and have a solid center pin. A loose plug is the usual cause of intermittent audio dropouts.
- Length
- Keep it to the length you need. Coax handles longer runs better than optical. Shorter runs reduce the chance of signal errors.
Brands that matter
- Monoprice: Inexpensive 75-ohm coax in many lengths.
- Mediabridge: Sturdier connectors and jackets.
- Hosa: S/PDIF coax aimed at pro gear.
What to avoid
- Paying a premium for 'audiophile' digital coax
- Generic analog RCA cables for long digital runs
Questions
Coax or optical?
Both carry the same compressed surround and stereo PCM formats. Coax locks in more securely and handles longer runs. Optical is immune to ground hum.
