Pass Labs HPA-1 Headphone Amplifier
The HPA-1 headphone amplifier was designed ground-up to become what we believe is one of the very best sounding headphone amplifiers available today. With low feedback, wide bandwidth and a direct coupled MOSFET output stage, this musical instrument drives even the most difficult headphone loads with ease, power and grace. The HPA-1 also functions as a line-level preamplifier that sonically rivals much higher-priced competition. The measured performance is superb and the sound even better.

Announcing the new Headphone Amp from Pass Labs!
Like the XP preamplifiers, the HPA-1 is the result of great attention to detail.
Starting at the power cord, the AC line is first filtered for high frequency noise and then isolated by a special toroidal transformer shielded by mu-metal for lower magnetic noise and shielded for electrostatic noise by a separate Faraday shield, grounded to analog ground. This is followed by fast/soft recovery rectifiers, generous CRC passive filtering and sophisticated discrete DC regulators and then more passive RC filters.
