“Overall my opinion of the Burson Audio HA160 headphone amp is a surprising one, especially to myself. This is the first solid-state amp I have ever used that I truly loved equal to, or even more than my tube based amps. The clean power the unique philosophy and the discrete engineering of this amp make it more than just another Head Amp, this desktop amp is a thing of beauty and is easily the equivalent of amps that are twice its price. “
