Advancing our tradition of unmatched audio performance and functionality, the Bryston BHA-1 balanced headphone amplifier delivers the finest listening experience from a vast array of headphone types. Functionally a miniature power amplifier, our engineers applied the same robust design elements to the BHA-1 that have made our full-sized amps legendary worldwide. Unique to the BHA-1, six class A, fully discrete operational amplifiers generate up to 2 watts of power for exceptional dynamic range. The BHA-1 offers both balanced outputs and single-ended outputs for traditional headphones, as well as a pair of rear-mounted XLR outputs that enable users to operate the BHA-1 as a high-quality analog preamplifier. Hear the best your headphones have to offer by powering them with a Bryston BHA-1.
