The Vincent SA-93 Plus is the kind of preamplifier that earns its keep by doing almost nothing — and that's exactly the point. A true dual-mono, fully balanced solid-state design with separate toroidal transformers and independent power supplies for each channel, it strips away crosstalk and noise floor artifacts until what's left is just the music, clean and dimensionally precise. Imaging sits with unusual specificity in the soundstage, bass lines have real pitch definition and weight, and there's a transparency to the mids that rewards good sources without mercy for bad ones. No romantic gloss, no softening — just honest, high-resolution German engineering doing exactly what a preamp should: staying invisible while the music speaks.

Liner Notes
The SA-93Plus is a remote-controllable Vincent stereo Pre-amplifier suitable for up to six input sources and up to four main amplifier channels. The functional and ergonomic, non-magnetic, polished aluminum chassis meets all quality demands. The stable metalwork represents a solid base for the electronic componentry.
Following the tradition of the model history, power supply and small signal amplification circuits are situated in separate cabinets to eliminate unwanted interactions between the fully regulated power supply and the delicate, low-level audio signals. At a closer look the power supply consists of two identical independent power supplies for the left and right channels that are driven by huge, custom-built toroidal transformers that feed the circuitry for both channels separately. Building up to this, circuitry for the left and the right channels have been kept apart in True Dual Mono Configuration, beginning at the rear panel source inputs leading to the pre-amplifier outputs to minimize crosstalk. The amplifier circuits use full-symmetrical FET modules. Even from unsymmetrical signal sources (as most CD-Players) symmetrical signals are being created to permit the usage of this technology for the connection between pre-amplifier and main amplifier.
All other sound-influencing electronic and electromechanical components (input selector, passive resistor volume controller, connecters etc.) have been selected carefully from premium-grade parts. The SA-93Plus features a brilliant Vacuum Fluorescent Display (with 1 lines and 13 characters) that indicates volume setting and source selection in bright, legible letters. The SA-93Plus is the ideal partner for the powerful Vincent main-amplifiers such as SP-993, SP-991 or SP-991Plus.
Packing
Prepare to be impressed. We have arguably the best packing process around. We use our InstaPak machine and white open cell foam to build a custom enclosure for your piece that ensures that it's stable and secure. If it is particularly fragile or heavy, we typically opt for private courier delivery. Depending on where you are in the country, that may cost a bit extra.
Shipping
This piece ships to the contiguous United States for a flat rate of $100, which includes our packaging and our insurance. Of course, we'll ship anywhere in the world, just drop us a line and we'll give you an estimate – even if you're just curious.
