Product Description

 

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 pre-amplifier that sonically rivals much higher-priced competition. The measured performance is superb and the sound even better.

  • Works with headphones with impedances of 15 ohms to 600 ohms
  • Low feedback wide bandwidth discreet design.
  • Class A – direct coupled Mosfet output stage
  • Custom low noise Torodial power transformer with a Farady shield
  • Discreet regulated power supply for audio circuits.
