Интегральные усилители — NAD C 700 V2

The NAD C 700 V2 is the second version of the brand's compact BluOS streaming amplifier, launched with a HybridDigital UcD power stage, a 5 inch display and HDMI eARC. Compared with the first C 700, NAD lists an upgraded DAC, a new moving-magnet phono input, Dolby Digital decoding, readiness for an optional correction licence and an included IR remote. Availability was announced for late August 2024 at USD 1,599, EUR 1,599, GBP 1,499 and CAD 2,199.

Key specs that matter

Continuous power stays above 80 W per channel into 8 ohm and 100 W into 4 ohm from 20 Hz to 20 kHz with both channels driven, with 120 W per channel of instantaneous power. IHF dynamic power is 100 W into 8 ohm and 125 W into 4 ohm, and clipping power exceeds 86 W and 102 W at 1 kHz for those loads. THD+N remains under 0.04 % from 250 mW to 90 W into 4 ohm. The A-weighted noise figure tops 84 dB, damping is above 90, and frequency response stays within 0.18 dB from 20 Hz to 20 kHz. Channel separation exceeds 93 dB at 1 kHz and 72 dB at 10 kHz, and line input sensitivity is 550 mV for full output. The housing measures 218 x 96 x 266 mm and weighs 4.8 kg.

Engineering and use context

Digital conversion now uses an ESS Sabre ES9028 chip, with high-resolution playback to 24 bit and 192 kHz as well as MQA decoding and rendering. BluOS provides access to around 20 music services, internet radio and local libraries, with AirPlay 2, Tidal Connect and Spotify Connect available next to Qobuz, Deezer, Idagio and Amazon Music HD. Dolby Digital decoding is built in for television sound arriving over HDMI. Multi-room playback extends to 63 zones. The glass HD screen shows album art, track progress and system settings. The unit can store up to five correction profiles once the separately sold licence is added, and a calibration microphone connects through the USB port.

Pairing

Sources connect through HDMI eARC, optical and coaxial digital inputs, one analogue line input and a moving-magnet phono stage that accepts a turntable without an external preamplifier. Two-way aptX HD Bluetooth can receive from phones or send to wireless headphones. The USB Type-A socket also plays music from storage, and a 12 V trigger output switches other components. Control is available from the BluOS Controller app for Android, iOS and desktop, through Alexa and Siri voice commands, or via major home control systems.
