Audio Interfaces on the Gear Hall

Audio Interfaces for Sale

Used audio interfaces from working sessions — Thunderbolt, USB-C, ADAT-expandable, and the older firewire-era pieces that are still serviceable today. Each listing shows the units the seller retired from a real studio, with the I/O count, condition, and any quirks called out before you ask.

Interfaces are the part of the rig that ages the slowest and appreciates the fastest — a 2018 Apollo Twin X still commands a real premium in 2026, while a duff Fireface that lost its PSU is worth parts at best. Sort by price to see what current sellers are asking for the units you’re shopping for, and read the condition note carefully: "Excellent" almost always means a working interface with light rack rash, while "For parts" usually means a specific channel or PSU is gone.

Common brands you’ll see on this page: Universal Audio (Apollo Twin, Arrow, Satellite), RME (Babyface Pro, Fireface UCX II, Digiface), MOTU (828es, 16A), Apogee (Duet 3, Symphony), Audient (EVO, iD44), and the Antelope units that cycled through home studios over the last decade.
