Easily integrate Hi-Res Audio, network streaming, and music control BluOS App in your C 390DD Direct Digital DAC Amplifier or Masters M12 Digital Preamp DAC. Featuring BluOS, the music management software developed by NAD’s sister brand, Bluesound, the DD-BluOS module is a complete digital music solution at an amazingly affordable price. Thanks to the forward-looking innovation of Modular Design Construction, you can now add BluOS network and internet music streaming with advanced music management to your NAD C 390DD or M12. As an internal module there are no external wires or power supplies required and integration with the C 390DD or M12 operating firmware is hand-in-glove. Both Ethernet and Wi-Fi operate in asynchronous mode for lowest jitter performance and allow connection to music stored anywhere on the local network or streamed directly from the Internet using a popular music services like Spotify Connect, Rdio, and Slacker. You can also play music from a USB drive or hard drive via the USB A port. In addition to a standard Local Area Network, BluOS requires an iOS or Android smartphone or tablet (NAD offers free iOS and Android Apps) to control and manage your music. While the expected functions of Play/Pause/Skip are present, BluOS also brings all of your music together integrating locally stored music (like iTunes) and music streaming services. BluOS does not rely on middleware like UPnP/DLNA/AirPlay with their inherent limitations, but instead creates direct shares with music in all formats including FLAC, ALAC and WAV with data rates up to 24/192. Playlists can be created and managed right inside the BluOS App. Gapless playback is supported and the DD-BluOS is fully compatible with Bluesound High-Res Wireless Multi-room Players to form integrated whole-house systems. Includes an external USB WiFi module to optimize signal strength.
The design of the HDA range draws upon all of Arcam’s experience as one of the UK’s most respected audio companies, to produce Arcam’s best performing range of audio products yet. The SA10 is a 50 W class A/B amp with an onboard MM phonostage and DAC. Note, there is no streamer, the Ethernet port is for monitoring and amp control only.

The M5si is a sensational integrated amplifier with exceptional power and clarity.

The M5si is a real high end amplifier. At 150wpc, with high current delivery, it will drive virtually any loudspeaker easily. Internally the M5si is configured as two independent monoblocs with a separate preamp, but all mounted on one pcb. Its technical performance is about equal to the M6si.

The M5si In Brief

  • 150wpc
  • Excellent technical performance
  • Preamp output
  • Unconditional stability, will drive any loudspeaker
  • Wide range of useful inputs including asynchronous USB and MM phono
  • Excellent hunky build quality

NAD has a distinct reputation for creating some of the best performing budget amplifiers of all time. The lineage is impressive, all the way from the 3020 of 1978 to the current C 328, with many “Best Amp” awards and five-star reviews along the way. The C 316BEE lived up to expectations, garnering multiple accolades including an EISA award for ‘Best Product 2008-2009’ and top recommendations from the world’s leading audio publications. With the resurgence of vinyl, NAD decided to update the design by including its highly acclaimed RIAA phono stage. This sophisticated circuit combines low noise with high overload margins to eliminate noise and distortion. RIAA equalization is extremely accurate (a rarity at this price) and there is even an infrasonic filter to reject airborne vibrations that can cause parasitic feedback.

Features

  • PowerDrive
  • 5 line-level inputs
  • MM phono input for vinyl
  • Front-panel input for portable media players
  • Bass and treble controls
  • Tone defeat
  • Headphone output
