Bryston Say….
Advancing our tradition of unmatched audio performance and functionality, the BHA1 is Bryston’s reference amplifier solution for the finest listening experience from your headphones. The BHA 1 is compatible with both traditional (single-ended) and balanced headphones.
The advantage of powering each headphone driver (right and left) with two amplifiers configured in balanced or series mode is a doubling of the signal voltage to each speaker. This design configuration has been the foundation of Bryston’s legendary 7B, 14B and 28B amplifiers and now headphone users can experience the same dramatic resolution from the BHA-1. The Bryston BHA-1 employs the vast benefits of balanced amplifier designs that are inherently clean and stable especially when there is a demand for higher power and/or a difficult load to drive.
Because most headphones are not balanced devices, Bryston provides a traditional (unbalanced) ¼-inch input on the BHA-1 as well as inputs for balanced headphones. Bryston will also provide modifications to some headphone models to make them compatible with a balanced output configuration, along with an adapter cable assuring backwards compatibility to all traditional (unbalanced) headphone outputs.
