“The first amplifier I gave up a lifetime obsession with tubes for”
Arnie Nudell, founder, Infinity Systems.

BHK amp shown in silver, also available in black

The
BHK Signature features a zero-loss vacuum tube input stage coupled to a
high bias deferentially balanced MOSFET output. This amplifier has few
rivals at any price and produces 250 watts per channel into 8 ohms. The
BHK Signature power amplifier culminates one man’s life long quest for
perfection in power amplification. Bascom H. King’s magnum opus combines
a vacuum tube input with a powerful MOSFET output capable of either
250/500 watts per channel in the Stereo 250, or 300/600 watts in the
mighty Mono 300. The BHK Signature Series amplifiers can drive any
loudspeaker to musical perfection and is the second most important
element in your music reproduction chain behind the loudspeaker itself.
