Welcome to Pass Laboratories.

We HAVE moved.

Our new phone number is: 530.878.5350

Pass Laboratories,
13395 New Airport Rd,
Suite G,
CA 95602


At Pass Labs we have one goal: to create products that invite you to listen.  We want you to enjoy the experience so much that you go through your entire music collection - again, again and again.... each time a joyous discovery of something new.  We want music lovers for the long haul.

To reach that goal, we continually strive to design amplifiers that deliver great sound, measure well and are reliable. This is achieved through ongoing R&D, and lots and lots of listening. Oscilloscopes and distortion analyzers are excellent tools, but they historically make lousy customers. Our real customers care most about the experience they get when they sit down to listen to their music.
