NAD C 338 Stereo integrated amplifier with built-in DAC, Wi-Fi & Bluetooth The C 338 uses an advanced Class D amplifier design for consistent performance. Its highly efficient power supply provides a noise-free foundation, generating huge power with negligible distortion — up to 1000 watts instantaneously to faithfully reproduce the energy and excitement of all your favorite music. A built-in high-performance headphone amplifier can drive even the most demanding studio monitor headphones. The NAD C 338 is equipped with built-in WiFi for a wireless connection to your home's wireless router and network. It uses dual band (2.4GHz/5Ghz) Wi-Fi (802.11b/g/n) for high-performance streaming. This wireless connection allows you to access Chromecast Built-in and Spotify Connect. Digital Inputs: The NAD C 338 is equipped with two optical (toslink) digital inputs and two coaxial (RCA) digital inputs. These digital inputs will support 2ch PCM audio up to 24-bit/192kHz (not compatible with Dolby Digital/DTS). Analog Inputs: The NAD C 338's stereo RCA inputs (2 Line/1 Phono) can accommodate all kinds of analog source components by offering ideal input impedance characteristics with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation caused by inappropriate loading of the source device.
