The Bi70mk2 is recommended for systems that are plagued by excessive vocal sibilance or "bright" highs. It resolves these issues by adopting a novel approach in amplifier design.

Unlike most conventional designs, the Mk2 combines a mosfet driver with a bipolar output stage. During listening tests, it was apparent that the Mk2 "cures" the abrasiveness in the mid and high regions, resulting in superior vocal clarity and imaging.

The Bi70mk2 Kit includes the power heatsink as shown on the right.
