We have this preowned Pass Labs HPA-1 Headphone Amplifier in Silver. It is in good condition, there is a slight mark on the cabinet which can be seen in the pictures attached. It comes with the original box/packaging & UK mains lead.
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.
