The Bryston BHA-1 is an impeccably designed and solidly built amplification device for speakers that you just happen to wear on your head. It has a fastidiously clean and neutral sound quality with an abundance of power and connectivity options that will allow almost any headphone to shine on its own merits. If you are in the market for a top-class headphone amplifier and don’t need a built in DAC, you really cannot go wrong with choose the BHA-1. Highly recommend!
