Sourcing digital music has never been easier
The 851N connects to your home network using Ethernet or Wi-Fi, giving you access to more than 20,000 Internet radio stations, Spotify and TIDAL streaming services, and music stored on networked laptops, home computers, and servers. The addition of AirPlay and high-quality AptX Bluetooth (available with the optional BT100 Bluetooth Audio Receiver Dongle) allows for streaming from compatible smartphones and handheld devices, while a variety of digital inputs (including coaxial, optical, and USB) open access to external digital components and memory sticks.
Advanced high-end music processing
While you’ll love the 851N’s ability to access limitless amounts of digital music, your entire system will benefit from its audiophile processing capabilities. It all begins with Cambridge Audio’s 2nd generation Adapted Time Filtering technology, which processes all incoming digital audio by stripping away jitter, eliminating distortion, and upsampling to a 24-bit/384kHz signal. That signal is then processed by dual Analog Devices AD1995 digital-to-analog chips deployed in a dual differential configuration – one for each channel – delivering precision stereo imaging loaded with detail.
If your digital music is stored on a computer, skip its paltry soundcard and tap the 851N’s incredible digital-to-analog conversion processor; simply connect your computer directly to the 851N via USB (Type B) and take advantage of the player’s Analog Devices DACs to enjoy every drop of detail contained in your favorite tracks.
Broad file support
The 851N supports a wide array of popular music formats through USB, network, and UPnP connections. Whether its compressed files such as MP3, AAC, WMA, and Ogg Vorbis, or true Hi-Res PCM, DSD, WAV, AIFF, ALAC and FLAC (up to 24-bit/192kHz), you’ll enjoy ear-pleasing audio quality capable of exceeding the limits of a typical compact disc.
It's a digital preamp, too!
While the 851N can feed any power amp or powered speakers with a true Hi-Fi analog signal, it can also be used to process your preferred digital sources. And unlike lesser digital preamps, the 851N’s onboard 32-bit Blackfin Digital Signal Processor doesn’t inflict bit reduction as you adjust your system’s volume. That means the digital signal’s integrity remains fully intact, loaded with purity and detail, no matter what volume you prefer.
Simple user-friendly app control
While the 851N’s front mounted color display and selector knob are a great way to explore your favorite artists and albums, Cambridge’s free Connect app (iOS/Android) is your ticket to a truly seamless user experience. The app offers simple and intuitive management of your preferred digital sources with functionalities such as browsing, playlist creation, and playback controls, all usable right from the comfort of your favorite chair.
Pair with an integrated amp
Because the Azur 851N Flagship Digital Preamplifier/Network Player has digital preamp capabilities, you can pair it directly with Cambridge Audio’s Azur 851 Series of power and integrated amps. Whether you choose the elegantly versatile Azur 851 Class XD Integrated Amplifier or the powerhouse Azur 851W Power Amplifier, you’ll experience Cambridge Audio’s signature sound like you’ve never heard it before!
