The King Headphone Amplifier, created exclusively for Audeze by legendary circuit builder Bascom King, especially matched with our flagship LCD-4 headphone, produces a powerful, dynamic and panoramic sound with awesome power in the bass. Upon first listen many are shocked by the tremendous sense of space; enveloping you-are-there sound that’ll make you jump! The King’s sound is so clean and engaging that you’ll turn up the volume to enjoy the immense transparency and palpable imaging. The utter pleasure The King delivers is totally addicting.
“It's just you and the music with amazing detail, awesome dynamic range, and the best midrange I've ever heard.” - Dan Gheorghe, Headmania
Why The King? Watch this video that explains it all.
The King’s circuitry is very different from the typical complementary output topology; it uses the same polarity N-channel MOSFET outputs as these are more alike and complementary than N- and P-channel MOSFETs. Just before the output stage is a two-stage differential amplifier using a dual-triode tube for the input stage followed by a P-channel MOSFET differential driver stage. The driver stage supplies complementary drive to the N-channel output devices. Overall negative feedback is taken back to the input stage to include the input triode in the feedback loop. The circuit is DC-coupled from input to output and a servo control circuit keeps the output DC offset to within millivolts of zero. The overall symmetry of the circuitry eliminates most even-order harmonic distortion. The result is a low impedance, low distortion, wide frequency response output with immense musical transparency, a real emotional experience.
