NAD C 399

While both amplifiers offer solid performance, the C 399 provides a more modern and versatile experience compared to the older C 370. The C 399 comes equipped with digital inputs, a built-in D/A converter, and Bluetooth functionality, making it suitable for digital and wireless audio sources, whereas the C 370 lacks these features. Additionally, the C 399 has a phono input for turntable connections, which the C 370 does not support, appealing to vinyl enthusiasts. The newer model also boasts a higher RMS power output of 180 watts, compared to 120 watts in the C 370, ensuring more power and headroom for demanding audio playback. Moreover, the lighter weight and inclusion of a display make the C 399 a more user-friendly and flexible option for contemporary living spaces.
