NAD C298 Stereo Power Amplifier (Trade In)

Description

The NAD C 298 Stereo Power Amplifier is designed to deliver exceptional clarity and control for high-performance music systems. Built around Purifi Eigentakt™ amplification, it allows loudspeakers to perform with greater precision and ease across a wide range of volumes. The C 298’s performance has earned international recognition from hi-fi and mainstream press, reflecting both its engineering and musical results. Designed to partner naturally with components such as the NAD C 658 BluOS Streaming DAC, the C 298 provides a stable, transparent foundation for advanced two-channel systems.
