The Good, Made Better

The SA-31MK is a development on the established SA-31. The outcome from the elaborate development work is a preamplifier which does not only have few competitors in terms of sound quality but also will never lose control under the most diverse connection circumstances and in connection with almost all main amplifier types.

The SA-31MK is configured with shorter signal paths than that of its predecessor. This results in a purer signal and therefore a sound with greater detail.

Best of Both World

Four type 6N16 tubes are used in the SA-31MK instead of two. The first two tubes are in the input section. Two more tubes sit in front of the output after the tone control. This results in a sound characteristic that is more natural and precise. 

Valve amplification is used in addition to transistor solid-state amplification to result in a pre-amp that sounds stupendously clear and is efficient in terms of power consumption.


The SA-31MK has a range of gain and tone-control options that allow you to make fine adjustments to the sound of your source material before it even hits the main amplifier. These controls can be switched off, to hear your content without any additional processing from the pre-amp.

Connection Options

The SA-31MK features a huge amount of connections for your Hi-Fi devices. With a total of 6 inputs and 3 outputs, this preamp enables almost endless connectivity options. 

The Perfect Match

The SA-31MK is the perfect match for the rest of Vincent's powerLine range!

Pair up the SA-31MK preamplifier with a quality power amplifier to turn your Hi-Fi system into a sonic powerhouse.

Sound Wonder
A duo that can enchant the substance out of the instruments. The metal strings of guitars shimmer, buzz and ring metallically, while the wooden guitar (or even a piano) body has a completely different base and overtone spectrum, which is reproduced here with a natural timbre.
