NAD's most Versatile Amplifier ever with ChromeCast built-in & Hybrid Digital Technology

The C 338 adds big sound to your favorite music sources and brings incredible flexibility to any stereo system. With Spotify Connect®, Bluetooth®, and the first-ever hi-fi amplifier to have built-in Chromecast®, the C 338 allows you to stream and cast music directly from any music streaming app, letting you enjoy your music wirelessly. Add a turntable using the phono input and experience the warmth of vinyl collections with the room-filling sound of NAD’s HybridDigital amp technology. Power, volume, source selection, and device settings are all controlled using the intuitive interface of the NAD Remote App for iOS and Android.

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.

Hybrid Digital 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 customized Hypex® UCD output stage to pump out 160 watts continuously and over 300 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 favorite 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.
