BRAND: Pass Labs
Pass Laboratories, Inc. was founded in 1991 by Nelson Pass. Operating out of his shop at home, Pass developed prototypes of a single-ended Class A amplifier design. At the same time, he and Mike Burley were constructing an in-house machine shop with three home-built CNC milling machines with which to produce the amplifiers when the design was finished.
XP17 uses the new-shielded low noise toroid and input filter module, like the XP-12. The power supply has an extra stage of RC filtering. We have lower radiated and mechanical noise.
The XP17 has an all-new input circuit that is symmetrical and lower in noise and distortion with greater drive capability. Noise is the most prominent part of THD+N in the first section of a phono stage. By lowering noise we get better resolution and dynamics.
Designed with a split EQ network like the XP 25 and XS Phono that is more accurate and can handle greater signal levels. The secondary stage runs a higher bias output stage with auto bias. The numerous loading options from the XP-15 are all still available and three gain settings to accommodate low output MC to MM cartridges.
