FREE SHIPPING within the continental United States.

The Bryston BHA-1 is a fully balanced Class A headphone amplifier engineered to deliver exceptional control, transparency, and dynamic range with a wide variety of headphones. Designed as a miniature high-performance power amplifier, it uses six fully discrete Class A operational amplifiers to produce up to 2 watts per channel.

Three stereo inputs—including balanced XLR, single-ended RCA, and 3.5 mm TRS—make the BHA-1 easy to integrate into a reference headphone system. Balanced and single-ended headphone outputs provide excellent flexibility, while rear-mounted XLR outputs allow the BHA-1 to serve as a high-quality analog preamplifier.
