Designed by the late Bascom H. King, the BHK600 represents the culmination of a lifetime of dedication and design in a single breathtaking expression of pure audio amplification. Built like no other power amplifier in history, the BHK600 will stand the test of time as one of the finest power amplifiers ever crafted. From the pure brute force of its massive 1.6kva power supply smoothed by 336,000 microfarads of capacitance to the delicate beauty of its vacuum tube rectification stage, the BHK600 will bring magic to your system from the first moment music is played. For those unwilling to compromise, the BHK 600 represents the final step in building a state-of-the-art high-performance music system.
