Audio Research Reference 20 Pre-Amplifier

The Reference 20 is the culmination of a singular objective: to advance beyond the established limits of preamplifier architecture and redefine what is possible in line-stage performance.

Developed without constraint, it represents a complete rethinking of the line-stage preamplifier. Every critical element—mechanical, electrical, and material—has been reconsidered in pursuit of one outcome: absolute sonic transparency.
