“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.”

As far as solid state amps go using a MOSFET transistor design this is the best headphone amp you can get. I’m obsessed with portability, so I can get away from my 2 yr old, I’m gonna spring for the woo audio wa 8 come November.
If I wasn’t I’d be all over this.
Whoever gets this amp your good for years to come.
