Vincent SP-332 Hybrid Stereo Power Amplifier

Vincent’s SP-331 hybrid power amp has been a company mainstay for years. The SP-332 is intended as an enhancement of the SP-331, upgrading it by providing both balanced XLR inputs and single-ended RCA inputs, selectable via a rear panel switch. This versatility makes the Vincent compatible with the widest possible range of preamplifiers on the market, and it will bring out the best in any quality preamp you pair it with.

The SP-332 also has dual speaker outputs, which can be individually switched on and off. This amplifier is the ideal partner for Vincent’s SA-32 or SA-31MK preamp, as well as DVD players, CD players, tuners, headphone amplifiers and loudspeakers from the Vincent range. However, you’ll also find that it partners beautifully with any high-quality audiophile components.

Inside the SP-332 are 6N16 tubes working in differential push-pull design in the input stage, giving the sound the classic warmth and richness that you can only achieve through the use of vacuum tubes. The solid-state output stage is powered by eight formidable FET transistors for the final amplification. These transistors provide 150 watt-per-channel at 8 ohms and will effortlessly drive even the most demanding loudspeakers.

In the power supply, a 500W toroidal transformer provides the muscle required for power on demand with 80,000 µF. This contributes to the highly accurate, profoundly powerful sound and deep, responsive bass. Voltage stabilization is provided by a 6N15 tube.

The most striking front panel feature is the new pair VU meters. The color backlight of these meters and the status LEDs can be switched between red, blue, green, or white light using a sliding switch on the back.
