Vincent Audio KHV-111MK Hybrid Tube Headphone Amplifier


Vincent Audio has introduced a high-quality headphone amplifier that uses a hybrid of vacuum tube and solid-state circuitry to enable serious headphone listeners to get the most pleasure out of their music.

The Vincent Audio KHV-111MK headphone amplifier combines premium solid-state discrete component circuitry with a classic 12AX7 vacuum tube input stage that is ideally matched to the headphone use. The 12AX7 is a two-channel, pure Class A triode vacuum tube noted for its high gain, accuracy and musical character.

With the higher operating voltages of vacuum tubes, and the different requirements of the solid-state sections, Vincent Audio gave the KHV-111MK a very large and stable power supply section. With the combined weight of the power supply combined with the heavy-duty chassis used to shield the sensitive circuitry, the KHV-111MK weighs in at a hefty 7 pounds, well above that of most headphone amplifiers.

The Vincent KHV-111MK has separate, front-panel volume controls for the left and right channels, a front 1/4-inch headphone jack, power switch, and a window to monitor the glow of the vacuum tube filament. The rear-panel has gold-plated stereo RCA input jacks.
