The output impedance of each output is quite low and thus able to better drive long
cable runs or cables with greater capacitance or amplifiers with low input
impedances.
XP-30 volume control is totally new and sonically unique. It's measured
performance - distortion, bandwidth, noise, and resolution is beyond reproach. It
preserves the dynamics and detail of the music passing through it, and scales this
performance over its 100 dB attenuation range.
Wayne Colburn has further refined his thinking of how the active circuit should serve
the music. Like Nelson, Wayne looks at parts and sees not applications but
potentials. The XP-30 uses a new and more advanced version of the gain modules
that have been popular in Pass products for the last ten years. It has lower
distortion and wider bandwidth than its predecessor and also features a dramatically
higher input impedance. This improved version of our symmetric topology sounds
so exquisite that that it has also been adopted in the new “Dual Chassis Amplifier”
prototypes. Pass Labs has made large purchases of discontinued Toshiba Jfets and
Mosfets to support production of this new gain stage for the next ten years.
Each of these efforts have contributed to a preamp that is more resolving, dynamic,
spatially accurate and closer to the real joy that is music.
To summarize:
The XP-30 is a time machine, offering a greater “look-back” at the original musical
performance and conveying additional insight to the artist’s creative intent. The XP-
30 will help you rediscover the joy of your record collection.
It's measured performance is our best yet.
It has some features that will help you get more out of your system – things that you
may not yet appreciate.
The XP-30 is the preamplifier that we built for ourselves.
