NAD C 338 Description

Getting the Basics Right
Built with NAD’s renowned music-first approach to audio architecture and amp design, the C 338 is equipped with the most advanced components commonly found in NAD’s class-leading line of amplifiers. Always starting with the details you can hear and advancing from there, NAD develops low-noise circuitry with the precision and stability to deliver incredible, near-zero distortion sound for the most difficult speakers.

HybridDigital™ Amp Technology
The search for a high-performance Class D solution led NAD to HybridDigital™, an innovative amplifier technology that uses a variable modulation frequency to bring out the life-like qualities of music, while reducing distortion under every operating condition. This highly optimized design gives phenomenal performance to the C 338 amplifier, both measured and subjective.

Efficient Class D Power
NAD has worked tirelessly to create the best performing Class D amplifiers that are energy efficient and produce beautiful sound—not heat—regardless of basic design principles. Using advanced measurements and data, NAD developed the C 338’s highly efficient power supply with a customised Hypex® UCD output stage to pump out 50 watts continuously and over 200 watts instantaneously to meet the demands of the most dynamic music. This new design is very linear over a wide bandwidth and provides consistent, noise-free performance for the amplifying stages with near perfect regulation of voltage.

Always Ready for Streaming
The C 338 has Chromecast built-in so you can cast music, tunes, podcasts, and playlists from your favourite apps on your phone, tablet or laptop to your stereo system. Spotify Connect® lets you discover millions of songs and stream them directly to your C 338 using the Spotify® app for a rich, wireless music experience. With the added flexibility of Bluetooth®, your music streaming possibilities are truly limitless with the C 338.

Built-in Phono Stage for Vinyl Listening
Using a MM phono stage and an innovative low-noise circuit path, the C 338 can reproduce the warmth of LPs with accurate RIAA equalization and control the infrasonic noise that is in all recordings, without ever affecting the bass response.

Flexible Connectivity
With a wide array of connections, including a separate headphone amplifier that can drive high-impedance studio monitor headphones, the C 338 is ready for any type of listening. Line inputs can accommodate all kinds of analogue source components, offering ideal input impedance with linear ultra-low noise buffer amplifiers to preserve the musicality of recordings. Also connect a subwoofer with low impedance line outputs and extend the versatility of this budget-friendly, do-it-all amplifier.
