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 lineoutputs that can connect to subwoofers extend the versatility of this well thought out amplifier. These are all details you can hear.
Connected and Smart
You can connect instantly to the C 338 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 338 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 NAD. The C 338 includes Wi-Fi and Network Streaming. It also provides access to internet radio stations and can serve as an UPnP Client for network streaming from a local NAS library.
NAD has moved away from the old-fashioned and power-hungry linear power supplies and Class AB output stages that waste nearly half of the energy consumed producing 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 someof 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 160 watts continuously and over 300 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 338. 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 338 uses a customized version of the proven Hypex UcD output stage. This allows for massive power with nearly unmeasurable distortion and noise in the audible range. Every detail of this amplifier has been carefully designed and perfectly executed to wring out every last drop of performance.
