PS Audio BHK Signature 250 Stereo Power Amplifier

Description

This stereo power amplifier is the industry reference standard for performance—an investment grade musical instrument that brings music to life. The BHK Signature 250 stereo is built upon two proven topologies: a zero-loss vacuum tube input stage coupled to a high bias differentially balanced MOSFET output. If you are uncomfortable with compromise and seek the finest performance, reliability, and build quality in a single-chassis format, the BHK Signature 250 is a perfect fit.
