XP 20 Owners Manual Rev 0.4 3
Introduction
The XP-20 is an ultra high quality line-stage audio preamplifier featuring an improved
hand held remote control and external power supply electrically isolated from the analog
circuits of the preamplifier in a cosmetically matched second chassis.
The XP-20 like all Pass Laboratories products attempts to minimize the number of
components in the signal path, and yet retain exemplary objective performance
specifications. This pre-amplifier pushes the edge of the art by exploring how much
subjective quality is obtainable with unique circuit elements applied in innovative ways.
The Pass Laboratories XP-20 along with the XP-10 pre-amplifiers are the natural
descendants to the highly acclaimed and successful X series of Pass Laboratories line-
stages represented by models X0.2, X1 and X2.5.
The X series pre-amplifiers have received many highly respected and well-deserved
accolades since their introduction in 1997…. justifiably so. More importantly they have
provided a solid foundation from which the current and newest product has evolved.
These new pre-amp offerings from Pass Laboratories objectively sound and measure
significantly better than their immediate predecessors. These are the finest pre-
amplifiers Pass Laboratories has built to date, without question! Thank you for your
purchase of the XP-20.
The new XP series pre-amplifiers are more true to state of the art recordings than our
previous product. Given quality recordings, these pre-amplifiers sound more dynamic,
bass lines are more clearly, cleanly, and accurately delineated, helping eliminate un-
necessary one note bass; instruments and voice are presented in a more refined spatial
envelope, and with better spectral balance. Fine nuances and details, which frequently
