NAD Electronics C 388 BluOS-2i Hybrid Digital DAC Amplifier Factory Refurbished
With MDC BluOS-2i Card Installed NAD's new classic amplifiers. Intelligent. Powerful. Efficient.
A prime example of what we stand for here at NAD, the C 388 Hybrid Digital DAC Amplifier is at the top of its class in the world of affordable amplification. An incredibly powerful amp, the C 388 employs NAD technologies to ensure that even the most demanding speakers can be driven to life-like listening levels without dynamic compression. Thanks to its advanced preamplifier circuit, the C 388 gives low noise at all volume settings, ensuring that you’ll be able to listen to your music without any distractions. Another technology that’s available to the C 388 is the BluOS™ module, a music management system that can stream your music library wirelessly across your home Wi-Fi network. You can also instantly connect to the C 388 with Bluetooth® giving you access to various streaming services. With the ability to accommodate a variety of sources both past and present, the C 388 is a remarkably flexible product that will become a core addition to your home audio system. Introducing the NAD C 388. Expansive Power with Unprecedented Flexibility.
The C 388 ties together all the critical elements of a top performing music system; music sources past, present, and future, in addition to providing a nearly unrestricted reservoir of power that allows your speakers to reveal every nuance of musical detail. This advanced amplifier includes many cutting edge technological breakthroughs developed by NAD over decades of creating affordable ultra-high performance audio components. Getting the Basics Right
It is surprising how many seemingly advanced products in the market today often miss many of the most basic requirements for satisfying performance. Low noise circuits, precise volume control action, accurate channel balance, proper input and output impedance characteristics, high overload margins and stability with difficult speaker loads.
NAD starts by getting these things precisely right and advances from there. We include an MM Phono stage with precisely accurate RIAA equalization, high overload margins, extremely low noise, and an innovative circuit to suppress infrasonic noise that is present on all LPs – all without affecting bass response. Our line inputs can accommodate all kinds of analogue 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. We include a separate headphone amplifier with low output impedance and very high output voltage capability – enough to drive even high impedance studio monitor headphones. Low impedance line outputs that can connect to other amplifiers or subwoofers extend the versatility of this well thought out amplifier. These are all details you can hear. Future-Proof Modular Design
This NAD exclusive feature allows you to customize your NAD amplifier with additional capabilities and features, now or in the future. The two available MDC slots can accommodate a variety of upgrade modules including additional Digital Inputs, additional Analogue inputs, and one of the most advanced Hi-Res Audio multi-room wireless systems available, the BluOS™ music management system developed by Bluesound. BluOS connects to your network and is controlled via smartphone, tablet, or desktop device to manage your music collection and connect to a growing list of high-quality streaming music services. Connected and Smart
You can connect instantly to the C 388 with Bluetooth® allowing you to stream music wirelessly from any Bluetooth-enabled device. The high performance aptX® codec is fully supported for true CD-quality sound. Bluetooth can also be used to listen to other sources connected to the C 388 via wireless headphones such as NAD’s own HP70. There is also a control app that allows your smartphone or tablet to control all functions of your C 388. Adding the optional BluOS Module provides access to your local area network via Wi-Fi or wired Ethernet connection and adds Hi-Res Audio streaming. The BluOS Module also makes the C 388 a singlezone streamer in a complete multi-room wireless music system that is fully compatible with BluOS-enabled music systems and wireless speakers. These are available in a variety of sizes and shapes to fit every room and extend the performance of your primary music system to create a warm ambience of sound in your home. Sophisticated Power
NAD has moved away from the old-fashioned power-hungry linear power supplies and Class AB output stages that waste nearly half of the energy consumed and produce heat rather than sound. Instead, we have developed even better performing circuits based on switch mode power supplies and Class D output stages. Once thought to be inferior to traditional topologies, NAD’s advanced work in this area has created some of the best performing amplifiers regardless of basic design principle. These new designs are very linear over a wide bandwidth and provide consistent performance into all speaker loads, providing a dramatic advance over previous models.
The power supply is capable of 150 watts continuously and over 250 watts instantaneously to allow for short-term musical transients. It can operate with any AC mains voltage from 100 to 240 volts and provides pure DC power to all the various stages of the C 388. This highly efficient supply also provides near perfect regulation of voltage across a wide range of conditions and provides a solid noise-free foundation for the amplifying stages.
The C 388 uses a customized version of the proven Hypex UcD output stage operating in a fully balanced bridge configuration. This allows for massive power with nearly immeasurable distortion and noise in the audible range. Every detail of this design has been carefully planned and perfectly executed to wring out every last drop of performance.
