Executive Overview

xp-10Pass Laboratories exhibited its high-end XP-10 and XP-20 2-channel preamplifiers which feature Pass Labs signature beveled billet aluminum front panels. Building upon the XP-10, the XP-20 upgrades to an isolated power supply to further enhance its performance. Both the XP-10 and XP-20 are housed in sleek chassis of brushed aluminum, measuring 17 inches wide by 12 inches deep by 4 inches high. The XP-20 has a second matching chassis for its external power supply, which can be turned on using the remote control. Both preamps furnish two balanced and three single-ended inputs. Like all Pass Laboratories designs, these products minimize the number of components and stages in the signal path, a design choice that is intended to reproduce the purist fidelity possible.
