Introduction

After having tested a Pass power amplifier and phono preamplifier, I could not wait to get my hands on a preamplifier, to complete the system analysis. The subject of this review is the venerable XP-20, which has been in the Pass inventory since 2009. It's a fully balanced design, with separate power supply chassis for low noise. The bench test results were quite surprising. Read on to see for yourselves.
