LS-3

LS-3 is an exciting new preamplifier that showcases the innovation of our team of dedicated solid-state engineers. While the LS-3 may look exactly the same as the LS-2, it represents a significant advancement in solid-state design and technology.

The core of the LS-3 uses a differential JFET-based input stage to enhance signal integrity and reduce noise, followed by a bipolar transistor-based voltage amplifier to ensure robust performance. Class A output stage delivers a warm and dynamic sound, making it an ideal choice for discerning audiophiles.

The LS-3’s signal path employs a meticulously designed dual-mono architecture, with each channel equipped with an independent power transformer. This configuration not only enhances channel separation but also contributes to a clearer, more immersive listening experience. Furthermore, the inclusion of a zero-gain cascaded voltage reference source and a linear power supply ensures optimal stability and performance.

The launch of the LS-3 marks Audio Research’s continued push in the limits of high-fidelity audio, perfectly blending cutting-edge technology with our unwavering pursuit of sound quality to create a preamplifier that delivers exceptional sound. This extraordinary product is sure to elevate your audio experience to new heights.
