Product Details
Expansive Power with Unmatched Flexibility
The C 388 seamlessly integrates music sources from all eras with an extensive power reserve that reveals every musical detail through your speakers. This advanced amplifier features NAD’s latest technologies, developed over decades of designing high-performance audio equipment, ensuring excellent power and audio fidelity.
Getting the Basics Right
Many advanced audio products overlook fundamental performance requirements, but NAD prioritizes these aspects. The C 388 includes an MM Phono stage with precise RIAA equalization, high overload margins, ultra-low noise, and an innovative circuit to suppress infrasonic noise, preserving bass response. Its line inputs support various analog sources with ideal input impedance and ultra-low-noise buffer amplifiers to prevent sonic degradation. The C 388 also features a dedicated headphone amplifier capable of driving high-impedance studio headphones and low-impedance line outputs for subwoofer connections, making this amplifier highly versatile.
Future-Proof Modular Design
NAD’s exclusive Modular Design Construction (MDC) allows you to upgrade the amplifier with additional features now or in the future. The C 388’s two MDC slots support upgrades like 4K video-capable HDMI switching, additional digital and analog inputs, and BluOS® – a high-resolution audio multi-room streaming system. BluOS connects to your network and is controlled through smartphones, tablets, or desktop devices, offering a growing range of high-quality music streaming services.
Connected and Smart
With Bluetooth® aptX®, the C 388 enables CD-quality wireless music streaming from any Bluetooth-enabled device. You can also connect wireless headphones to listen to any source connected to the C 388, such as NAD’s own HP70. The C 388 also has a mobile control app for managing all amplifier functions. Adding the BluOS Module enables access to your network via Wi-Fi or Ethernet, supporting Hi-Res audio streaming and making the C 388 a single-zone streamer in a complete multi-room music system compatible with BluOS Enabled devices and speakers.
Sophisticated Power
NAD has moved away from traditional, power-hungry linear power supplies and Class AB output stages, opting for highly efficient switch mode power supplies and Class D output stages. These modern designs provide consistent, linear performance across all speaker loads, representing a substantial improvement over previous models.
The C 388 delivers 150 watts continuously and can handle over 250 watts instantaneously for dynamic musical peaks. This versatile power supply operates across all AC mains voltages (100 to 240 volts) and provides pure DC power to every stage, offering noise-free and stable power regulation.
Using a customized Hypex UcD output stage in a fully balanced bridge configuration, the C 388 provides substantial power with virtually undetectable distortion and noise within the audible range. Every aspect of the design has been meticulously crafted to maximize performance, making the C 388 a true powerhouse for any serious audio system.
