Black Lion Audio B173 Quad

The Lion Audio B173 Quad is a powerful four-channel preamplifier that combines the sonic characteristics of the legendary 1073 in a compact 2U rack unit. With a gain of 70 dB, it offers ample headroom and allows the use of low-gain ribbon microphones for quiet sources. The combination of high-quality components and discrete Class-A circuitry delivers an impressive sound richness with deep bass, clear mids, and brilliant highs. The transformer-coupled input and output stages contribute to a warm and robust sound, while the revised amplifier stage and reduced background noise ensure a clearer sound with less distortion. The B173 Quad is not just a clone of the 1073; it also offers modern features that meet the demands of even the most discerning audio engineers.
