Vincent Audio SA-31MK Hybrid Vacuum Tube Preamplifier


Vincent Audio SA-31MK Hybrid Vacuum Tube Preamplifier - Back

Vincent introduces a step-up version of its most popular stereo preamplifier with added remote control and improved Class A vacuum tube output stage.

Vincent Audio has introduced the SA-31MK a higher performing step-up version of its popular SA-31 hybrid solid-state, vacuum tube line-stage preamplifier. The new SA-31MK incorporates new output circuitry with two more vacuum tubes, precision European resistors and capacitors, electronic volume and input controls, two added line inputs, and the addition of a wireless remote control.

The Vincent SA-31MK is clearly much more than just an upgrade of the SA-31’s convenience features. The output stage incorporates a proprietary new design configuration with a short signal path using two 6N16 vacuum tubes that allow a detailed and delicate soundstage. The final output stage is a Pure Class A design using two additional 6N16 tubes. The new SA-31MK has a very substantial power supply with a large toroidal power transformer that ensures all the circuit elements have a rock-steady voltage supply and never lack for current when needed.

The SA-31MK adds full wireless remote control capabilities with a precision electronic volume control, and six remote-selectable line inputs.

The new Vincent SA-31MK is currently available in black or silver at a suggested retail price of $1,399.95. The SA-31 continues in the line at $649.95.
