Hybrid Digital Amplification: 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, NAD has developed even better performing circuits based on switch mode power supplies and Class D output stages. Once thought to be inferior to traditional topologies, this new Hybrid Digital Amplifier design is very linear over a wide bandwidth and provides consistent performance into all speaker loads, providing a dramatic advancement over previous Class AB and Class D amplifier designs.

• Customized Hypex UcD Output Stage: The NAD C 700 uses a customized version of the proven Hypex UcD output stage for effortless reproduction of musical transients. The HybridDigital UcD amplifier design offers massive power with nearly un-measurable distortion and noise in the audible frequency range, regardless of the loudspeaker load. Every detail of this design has been carefully planned and perfectly executed to deliver every last drop of performance.
• Sophisticated Power Supply: The power supply is capable of 80 watts continuously and over 120 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 NAD C 700. 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.

Full Disclosure Power (FDP): NAD uses Full Disclosure Power (FDP), the most demanding criterion for performance measurement. FDP specifies distortion under the most extreme conditions of low impedance loads and frequency extremes, rather than the simple and easy 1kHz @ 8 ohms test quoted by many of other manufactures. NAD uses this stricter performance criterion because it more closely matches the demands of real music and real loudspeakers. Maintaining specified distortion at 4/8O and at 20-20kHz is a much more difficult achievement. The benefit of NAD's Full Disclosure Power is the total elimination of audible distortion at any listening level. This provides pinpoint imaging and realism with music and movies alike.

• Continuous Power: 80 watts x 2 channels into 8-ohm or 4-ohm (@ 20-20kHz with 0.04% THD) - both channels driven
• IHF Dynamic Power: 120 watts x 2-channel into 8-ohm or or 125 watts x 2 channels into 4-ohm

High Resolution Audio: High-resolution audio tracks are either 24-bit/96kHz or 24-bit/192kHz, and contain up to 6.5x more data than standard CDs, letting you hear all the detail of your favorite music in superior quality. With full support for hi-res audio, you can stream WAV, FLAC, ALAC, AIFF, WMA-Lossless, MQA music files over your home's WiFi network or directly from a connected USB mass storage class device. The NAD C 700 also supports compressed music files such as MP3, AAC, WMA and OGG. The NAD C 700 has been designed to work with today's larger music collections, and has indexed libraries up to 200,000 songs in demonstrated practice (this will depend on the music's metadata & artwork). The C 700 also offers gapless playback by default for all supported file music types.

Notes: You cannot index or play AAC files with the extension ".m4p". These files were purchased in iTunes prior to 2009 and are subject to copy protection. Apple Consumers with an iTunes Match subscription can delete and re-download these files free of charge from their iTunes Cloud

MQA (Master Quality Authenticated): Bluesound is the first wireless multiroom audio system to support MQA (Master Quality Authenticated). MQA is a revolutionary end-to-end technology that captures and delivers master quality audio in a file that's small enough to stream or download. Bluesound worked closely with MQA to implement technology inside each Bluesound component to ensure the listener will hear MQA encoded music and streams exactly like the source and the way the artist intended you to hear it when it was approved in the studio.

Binding Post Speaker Terminals: The NAD C 700 integrated amplifier is equipped with four binding post speaker terminals to connect a pair of loudspeakers. The binding post terminals will accept bare wire (up to 12AWG), pin-connectors, spade-lugs, and banana plugs (single only). Plastic inserts will need to be removed from the binding posts to connect banana plugs.
