When musical vibrancy and sparkling audio energy are perfectly in harmony, only then can a pure Class A tube preamplifier offer unsurpassed sonic performance.

There is no doubt that the preamplifier is the heart of any high-end audio system, and the Lab12 Pre1 was designed from the ground up as a high-performance preamplifier, capable of serving both solid-state and tube power amplifiers.

We made no compromises at any stage of the design. Despite the Pre1's affordable price, it effortlessly injects purity and musical energy into any power amplifier, delivering an organic, transparent, and highly engaging sound.

The Pre1 operates with a fully tube-based core. A matched pair of 6922 tubes and a specially designed gain stage allow you to rediscover your music. Lab12’s unique four-stage regulated solid-state power supply provides state-of-the-art filtering and an enormous power reserve, capable of handling the most demanding musical dynamics, ensuring you feel and connect with the performance in full.

Pre1 is a true dual-mono preamplifier, featuring Lab12's exclusive Fine Symmetry® and SRSG® topologies at every stage. Countless hours of listening and a meticulous selection of high-quality audiophile-grade components reveal a sound that is rich, dynamic, transparent, and high-definition, exceeding even our own expectations for this price point.

The Pre1 represents our deep respect and love for music, preserving the purity of the recording and adding as little of its own character as possible. This is the preamplifier that will win over the hearts and ears of even the most discerning audiophiles.

As with all Lab12 products, the Pre1 is available in two anodized matte finishes: Black and Frozen Silver.
