Pass Labs, Inc. was founded in 1991 by Nelson Pass, a well-known figure in the audio community. Pass began developing a unique prototype out of his shop at home. That prototype, a single-ended Class A amplifier, became what many acclaimed as the “amplifier of the decade” in Stereophile magazine.

Pass Labs soon become one of the most prestigious brands in the audio world. Their patented SuperSymmetric technology and timeless designs paved the way for their products to date, many of which still incorporate components used in their original creations.
