The NPX 300 is a power supply designed to enhance your audio experience by improving the performance of 200 Series sources and preamplifiers, most notably the NSC 222 streaming preamplifier. By deactivating the internal power supply, the NPX 300 plays a crucial role in minimizing noise and boosting power efficiency, ultimately leading to cleaner and superior sound quality. This power supply allows the preamplifier to dedicate itself entirely to signal control, offering an enriched auditory experience. Notably versatile, the NPX 300 supports the connection of multiple units, enabling users to further refine and elevate their sound quality. This flexibility caters to audiophiles seeking to maximize the potential of their audio systems, ensuring outstanding performance and a high-fidelity listening experience.
