At its core, the LS-3 utilizes a differential JFET-based input stage, which enhances signal integrity and reduces noise, followed by a bipolar transistor-based voltage amplifier that ensures robust performance. The Class-A output stage delivers a warm and dynamic sound, making it a perfect choice for discerning audiophiles.

The signal path in the LS-3 is meticulously designed with dual mono architecture, featuring separate power transformers for each channel. This configuration not only enhances channel separation but also contributes to a cleaner, more immersive listening experience. Additionally, the inclusion of a zero gain cascaded voltage reference and linear power supplies ensures optimal stability and performance.

With the LS-3, Audio Research continues to push the boundaries of high-fidelity audio, delivering a preamplifier that combines cutting-edge technology with the passion for sound quality that has defined our legacy. This remarkable piece of equipment is set to elevate your audio experience to new heights.
