Warm-Sound M4 Class A Preamp Board

A dedicated audiophile preamplifier board built around Class A operation for natural harmonic expression and low-intermodulation distortion. Constructed on a black PCB substrate with no stated dimensions or weight. Core components include the 58AG92M dual-precision op-amp in a gold-plated socket, engineered for sweet midrange, extended high-frequency clarity, and authoritative bass extension. The board integrates two large unified heat sinks, extra filtering capacitors, balance trim adjustment, and selectable gain via amplification factor conversion. Its TL431-based regulated power supply delivers precise, low-noise DC to the op-amp — outperforming generic regulators in stability and channel matching. Mild heat generation during operation is expected and safe — a known trait of true Class A biasing. Setup involves only connecting input signal and DC power — no drivers, software, or external tuning required.
