  • Advancing our tradition of unmatched audio performance and functionality, the BHA-1 Balanced Headphone Amplifier is our solution to delivering the finest listening experience from your headphones. Functionally a miniature power amplifier, we applied the same robust design elements to the BHA-1 amplifier that we used to develop our full size amps. Six class A fully discrete operational amplifiers generate your headphone output, delivering up to 2 watts of power for more than adequate dynamic range. The BHA-1 provides a true balanced mode via balanced outputs, or you can use the single-ended outputs for more traditional headphones. The BHA-1 also has a pair of XLR outputs which allow you to use the unit as a high quality analog preamplifier. Hear the best your headphones have to offer by powering them with a BHA-1.
