About the RS-28CX
The Leben RS-28CX is a premium preamplifier known for its high-quality components and robust output capabilities. It uses General Electric (USA) tubes, including the 6CG7 and 12AT7, to provide a clean and strong signal. The preamplifier includes a CR type equalizer for precise RIAA curve reproduction and a 5-step attenuator to reduce residual noise. It supports integration with a subwoofer via two outputs (one fixed and one variable). The RS-28CX is praised for its lucid sound across the frequency spectrum, low noise level, and dynamic performance.
