Audio Research LS16 Tube Preamp

•⁠  ⁠Overview – Audio Research LS16 Tube Preamp, released in 1999, is a fully balanced solid-state and tube hybrid line-stage preamplifier using vacuum-tube gain stages to deliver classic Audio Research neutrality with musical warmth and dynamic authority.

•⁠  ⁠Circuit Design – Built around a dual-triode tube topology with balanced architecture, it offers exceptional transparency, wide bandwidth, and low noise, making it ideal for revealing power amplifiers and high-resolution source components.

•⁠  ⁠System Matching – The Audio Research LS16 Tube Preamp excels in resolving micro-detail and soundstage depth while maintaining tonal balance, pairing especially well with both tube and solid-state power amplifiers in reference-level systems.

•⁠  ⁠Specifications – Utilises four 6922 dual-triode tubes, fully balanced outputs, multiple single-ended and XLR inputs, low output impedance, and high voltage regulation for stable operation and consistent sonic performance.

•⁠  ⁠Dimensions – Approx. 483 mm (W) × 133 mm (H) × 356 mm (D), housed in Audio Research’s classic brushed-aluminium chassis designed for proper ventilation and rack-friendly installation.

•⁠  ⁠Weight – Approximately 10 kg, reflecting a robust internal power supply, shielded circuitry, and solid mechanical construction that supports long-term reliability and low microphonic behaviour.
