From its incredible dynamic range, three-dimensional soundstage to its ability to reproduce the finest micro details. Unlike the general-purpose IC opamp designs, which focus on high open loop gain, Burson aimed to achieve low open-loop distortion, low noise, low drift and low offset. Better power = better sound.
