Network powerhouse

  • The 851N is a network player designed to draw every last drop of detail from every digital audio source.
  • It will make streaming and digital audio from phones, laptops and set-top boxes sound better than you thought possible.
  • Designed from the ground up for serious performance, it’s not only bristling with inputs and outputs, but also internally configured with high-end components.
  • The result is the most versatile, powerful digital network player we have ever made.

High-resolution performance

  • The 851N features our renowned ATF2 24-bit/384kHz upsampling.
  • Our unique ATF2 (Adaptive Time Filtering) doesn’t just draw extra detail from every source (even CD, Blu-ray and “lossless” digital files), but also virtually eliminates “jitter” common in playing digital audio files ? which can lead to a flatter, lifeless sound with tinnier bass response.
  • The feature-packed 851N also offers 24-bit/192kHz native input from all sources ? USB, digital inputs, ethernet and wi-fi.
  • So however you store your high-resolution files, the 851N will ensure they sound as the creators intended.

All bases covered

  • However you like your digital music, the 851N can handle it. With 5 USB sockets, 2 optical digitals, 2 coaxial digital and XLR digital inputs, plus ethernet and wi-fi,
  • The 851N is designed to cope with every source you need: Blu-ray, smartphones, tablets, laptops, games consoles, CD, set-top boxes and more.
  • As you’d expect, outputs are similarly high-end and wide-ranging, including XLR balanced and RCA unbalanced analogue, digital optical and coax, and IR control repeater
  • So you can hide 851N in a cupboard ? although there?s no need to hide the stunning colour screen.

High-quality design

  • The 851N is designed inside and out not just to deliver the stunning audio quality, but to look beautiful as well.
  • A new 4.3-inch TFT colour display shows current album artwork and more, while control is via remote or smartphone app.
  • And the discreet all-metal chassis includes rigid aluminium front, top and sides not just to look good, but to also minimise vibration and maximise audio quality.

Versatile performance

  • The playback options are extensive ? Spotify Connect, Apple AirPlay, Internet Radio, USB with DSD, MP3, AAC, WMA, as well as lossless formats including FLAC,
  • Apple and Ogg Vorbis. Digital audio connections in and out are covered, so are all major digital streaming services and so are all common digital audio formats ? including the highest-resolution ones used to store or stream audio.
  • And all in 24-bit/192kHz stunning high-definition clarity.
  • The 851N is also compatible with an optional BT100 to allow for Bluetooth streaming, and with internal processors that are upgradable via an internet connection,
  • The 851N is a very future-proof and functional network machine.

Raw power

  • Twin AD1955 digital-to-analogue converters (DACs) configured in mono mode ensure maximum fidelity to both left and right signals,
  • A fully linear power supply makes maximum use of the audiophile-grade toroidal transformers inside and a brand new Zander processor enables not just 24-bit/192kHz streaming over wi-fi, but also a much quicker and more intuitive user interface.
