Three years ago Burson Audio developed their HA-160 headphone amplifier. Instead of using standard IC opamps on the signal path, Burson Audio designed their component, using high quality discrete components – with the objective of optimizing operation and offering higher resolution and superior dynamics.

The new Soloist headphone amplifier / preamplifier is an evolution of Burson’s headphone amplifier technology, utilizing fewer components (21 components – 30% less than the previous HA-160) in the signal path, while providing increased performance.
