NAD Master 2-614
NAD Masters Series
Many of NAD’s new technology innovations are first introduced in this flagship series. World-class fit and finish reflect the advanced design and features enclosed within.


Digital Music Player with 2TB Storage, CD Ripper, Wi-Fi and Bluetooth

A hybrid of NAD’s renowned M50 and M52, the M50.2 Digital Music Player offers everything you need to hear the music you love in the best quality possible. Harnessing the power of BluOS®, the M50.2 allows you to organise and store your music library, while making it easily accessible via the BluOS app. A high resolution network music player, the M50.2 was designed to house 24/192 files whether it be from a CD or music download site. The M50.2 CD transport can playback or rip to internal storage, and ripping is completely automatic. You can also connect to the M50.2 via Bluetooth®, opening the doors to virtually any music streaming service. The M50.2 brings you closer to your favourite music and makes it remarkably simple to access it. A wondrous integration of hardware and software, the M50.2 has 2TB of storage and a mirrored backup, ensuring you’ll never have to sacrifice any music or worry about losing it.

Take Two

When we introduced the M50/M51/M52 Digital Music Suite in 2012 (in honour of our 40th anniversary) we were betting that audiophiles around the world would embrace the new digital format of High Resolution Audio. These ‘highest quality’ recordings were just becoming available to consumers. For music lovers it was a dream come true. Exact copies of the Studio Master could now be easily downloaded, stored, and played back at any time in the home. Music lovers could finally get all the music the artist created. The Masters Suite makes it easy to download these high-res music files and securely store them, without reverting to using a computer for this task.

A lot has changed since we introduced the original Masters Digital Music Suite, but the M50 has kept abreast of these changes because of the incredible power of BluOS. This proprietary music-only operating system can be remotely updated to include new features and access to new sources of music. BluOS brings all your music together, from timeless CDs to cutting edge 24/192 downloads; all are organised and easily accessed via the BluOS app.

Now, high-res music listening, multi-room wireless streaming, 24/192 storage and CD ripping can all be found in one beautiful component: the M50.2. With 4TB of internal redundant storage featuring programmable RAID backup, this is a complete music solution that does not require a computer and is not prone to the viruses and program conflicts encountered when using a multi-purpose computer for music storage and playback. The M50.2 is a noise-free component that offers state-of-the-art digital performance and requires no additional programs to buy. Just add the DAC of your choice and enjoy.

Digital Music Player

The M50.2 is a “software defined” product, meaning that much of the functionality of the system is defined by software not hardware. This means that new cloud services or audio codecs can be integrated at a future date by simply updating the software of the M50.2. This software upgrade potential means that there is a software ‘roadmap’ that allows the M50.2 to live on and maintain its cutting edge functionality.

Hands-free Voice Control with Alexa

Add the BluOS Voice Skill inside the Amazon Alexa app and enjoy hands-free voice control of personal music collections, streaming services and more using a list of simple streamlined commands. Using an Echo device you can ask Alexa to play popular songs from Tidal, queue up saved playlists, adjust the volume in different rooms, or ask what’s playing in the Kitchen. No Echo device and want to try it out? No problem. Download the Amazon Alexa app, activate the skill, tap the speech bubble in the bottom drawer of the Amazon Alexa app and say anything from the list of commands.

Since its introduction, the original M50 has added TuneIn Internet radio tuner, Spotify, Tidal, Qobuz, Deezer, iHeart Radio, Murfie, and many more. We also include ‘direct download’ of High Res Audio from and, allowing you to purchase and download new music from right inside the BluOS app. The new M50.2 uses the same BluOS software, but has added some hardware features like a new, more powerful processor and Bluetooth 4.0 with aptX for direct audio streaming from a wide variety of popular devices.

Remarkable Performance

The hardware of the M50.2 includes the latest generation of low power, super high performance ARM processors that one can find. These have more computing power than a PC, yet run cool and do not require noisy fans. Many different digital outputs are supported in the hardware including SPDIF and HDMI.

The Choice is Yours

There is a choice of wired or wireless network connection using standard Wi-Fi protocol IEEE 802.11 b/g/n. While it is possible to stream 24/96 music wirelessly, we recommend a wired connection or local storage for HD music to avoid any possibility of dropouts. The Wi-Fi capability does offer the option of control from a smartphone or tablet with Wi-Fi, which is a fantastic way to enjoy your music collection. The M50.2 CD transport can playback or rip to internal storage, and ripping is completely automatic. The BluOS app with a network connection to the Internet, allows this music management software to fetch metadata and cover art; organised and instantly available for playback without the need for a computer. You can browse your music collection using album art or category listing, and easily create playlists on the fly.

Master Quality Authenticated

Master Quality Authenticated (MQA) is a revolutionary end-to-end technology built into every Bluesound Player that captures and delivers master quality audio to any room in your home. All Bluesound Players include a powerful decoder and audio renderer for the MQA system. The MQA logo shown in the BluOS app indicates that the unit is decoding and playing an MQA stream or file, and lets you know that you are hearing exactly what the artist recorded and approved in the studio.

CD Ripping & HDD

Master Series Digital Music Player: A hybrid of NAD's renowned Master Series M50 Digital Music Player and M52 Digital Music Vault, the M50.2 Digital Music Player combines high-res music listening, multiroom wireless streaming, 24-bit/192kHz storage, and CD ripping into one beautiful component.

Note: Pair the M50.2 Digital Music Player with one of NAD's Master Series' preamplifiers and power amplifiers, integrated amplifiers, stereo receivers, or AV receivers (all sold separately).

CD Transport: The NAD M50.2 Digital Music Player features a front-loading CD slot. The built-in CD transport can playback Audio CDs (CD-A) only. The M50.2 will automatically start playback of an inserted CD. Playback is different and much improved in the M50.2 over conventional CD players. Instead of streaming directly from the disc to the output, the M50.2 momentarily stores the data in a memory buffer where it is re-clocked to the M50.2's high precision master clock for the lowest levels of jitter.

Disc Ripping: The M50.2's CD transport can rip an inserted Audio CD directly to its built-in HDD thanks to NAD's own music management software. Ripping is completely automatic. With a network connection to the Internet, this music management software captures metadata and cover art, without the need for a computer. Everything is organised and instantly available for playback. You can browse your music collection using album art or category listing, and easily create playlists on the fly. You can choose to rip your Audio CD music as MP3 or FLAC files.

  • MP3 (default format): Standard audio compression designed to keep bandwidth low with little degradation. Files are ripped at 320kbps, the highest level of sound quality available to MP3 format.

  • FLAC (recommended format): High quality compression designed specifically for CD backup purposes. Files are ripped at FLAC level 5 balancing compression and rip speed at full CD lossless levels of 44.1kHz/16-bits

  • Both: For Hi-fidelity quality playback with the ability to export or download to a personal MP3 Player.

Note: When ripping multiple CDs, insert the next disc as soon as the current disc is ejected (it is not necessary to wait for the encoding to be completed before the next disc is inserted). Only Audio CDs can be ripped. It will not rip Blu-ray, DVD, DVD-Audio, HD-DVD, or other types of Optical Disc format. The CD ripping procedure can be stopped at any time by selecting "Eject CD".

HDTracks Ripping: You can also purchase, download, and store high-res tracks (up to 24-bit/192kHz) from HDTracks on the built-in HDD with no computer needed.  Now, you'll be able to access and share your entire digital music collection and stream it in studio-quality quickly and easily.

Internal Hard Disk Drive (HDD): The NAD 50.2 Digital Music Player features 4TB of internal redundant storage featuring RAID backup. You get 2TB of music storage with another 2TB of mirrored backup storage. Inside the NAD M50.2 resides an ultra-low noise 2x 2TB (Terabyte) HDD array. These special low noise media hard disc drives run cool and completely quiet. Unlike HDDs made for general computing, the M50.2 drives do not require fans for cooling.

Note: Audio files stored on the HDD can be played back at the M50.2 and wirelessly distributed to other Bluesound components in your home for multiroom playback.

RAID 5 Technology: The M50.2 Digital Music Player  provides a high level of protection for your valuable digital music collection. Using a Redundant Array of Independent Discs (RAID 5) technology, the M52's two 2TB hard disc drives (HDD) make it nearly impossible to damage your music. Front panel LED indicators display the status of the HDDs, and alert you if there is an HDD failure. Even if a disc drive fails, you won't lose data; simply replace the drive, and the system automatically reconfigures itself.


Network & Bluetooth Integration

Wired or Wireless Network Connection: The M50.2 Digital Music Player connects to your home network via a hardwired Gigabit Ethernet (RJ-45) jack connector or wireless WiFi (802.11 b/g/n; 2.4GHz) connection. Either network/internet connection allows you to stream music from the built-in HDD, online music services, or your Windows or Mac computer.

Bluesound Wireless High-Resolution Audio Eco-System: The NAD M50.2 is part of Bluesound's wireless high-resolution audio eco-system. The Bluesound wireless high-resolution audio eco-system consists of music players, amplifiers, hard-drives, and wireless speakers to playback your high-res and low-res music files, along with your favourite online music services throughout your home using your home's WiFi network. With an advanced WiFi antenna design and blazing ARM Cortex9 Processors, Bluesound ensures a solid connection in every corner of your home. Play your music in perfect sync or play different music simultaneously to any Bluesound device in any room.

Supported Music Formats: The Bluesound wireless audio system supports both low-res and high-res audio files; including MP3, AAC, WMA, OGG, FLAC, ALAC, WMA Lossless, MQA, WAV, and AIFF. Bluesound has been designed to work with today's larger music collections, and has indexed libraries up to 100,000 songs in demonstrated practice (this will depend on the music's metadata & artwork). Bluesound also offers gapless playback by default for all supported file music types.

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.

Inputs & Outputs

Dual USB (Type-A) Ports: The NAD M50.2 is fitted with two USB (type-A) ports to connect select USB mass storage devices with music files.
