About
Cao Labs is a personal collection of vintage and antique audio equipment — microphones, amplifiers, and speakers from another era. Every piece is personally sourced, tested, and honestly described.
We believe great audio equipment deserves a second life. Whether you're outfitting a studio, restoring a vintage system, or simply drawn to beautiful objects that also happen to sound extraordinary — you're in the right place.
Based in California.
