Vincent Audio SA-32 Tube Hybrid Preamplifier

Vincent’s SA-31 preamp has been a mainstay in the company’s portfolio of hybrid preamps for a long time. In fact, it was only Vincent’s second preamp and was launched in 1996 and replaced the LS-1. Its longevity is a testament to its uncompromising performance.

The SA-32 is a multi-purpose and robust stereo preamplifier that replaces the mainstay of the company, the legendary SA-31. 

The amplifier circuitry of this preamplifier combines the advantages of solid state and tube circuits. It is the ideal partner for Vincent’s SP-331/SP-331MK power amp, 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.

In comparison to its predecessor, the SA-32 uses four 6N16 tubes instead of only two, with two in the input section, and two at the output after the tone control. 

In addition to the RCA inputs and outputs used by the SA-31, the SA-32 includes balanced XLR connection terminals. A high-quality XLR cable (length 1.0M) is included. Vincent also provides a beautifully made remote control with an aluminum case.

The loudness function of the SA-31 has been replaced by a gain decrease. Therefore, pressing the front panel switch decreases preamp gain by 8 dB for high-gain power amps or extremely sensitive speakers.
