NAC-N 172 XS
The best of both worlds.

The NAC-N 172 XS defines a creative point at which two worlds collide – the traditional world of separate pre and power amplifiers, and the new world of network streaming.

For a start, the NAC-N 172 XS is a very high performance and inherently musical preamplifier. It combines a mix of analogue and digital audio inputs, a digitally-controlled analogue volume control, and analogue outputs to connect to a power amplifier. And it offers even more besides, because along with its conventional inputs it includes a front panel USB audio interface for iPad, iPod and iPhone input, and a wired or wireless network connection to access internet radio stations or stream from UPnP music servers.

Features
  • High quality preamplifier including digitally controlled analogue volume control
  • UPnP-enabled to allow streaming of audio files at up to 24bit/192kHz resolution from Naim hard disk servers, network-attached storage (NAS) devices or any home computer
  • Supports a broad range of music formats: WAV, FLAC, Apple Lossless, AIFF, AAC, Windows Media-formatted files, Ogg Vorbis and MP3
  • Six 24bit/192kHz-capable digital inputs (S/PDIF) to support optimum connection to external sources
  • Optional DAB+/DAB/FM radio module
  • vTuner 5* full-service internet radio
  • Multiroom & Party Mode compatible
  • iOS and Android Naim app for intuitive control
Technology & Craft

As the first Naim streaming preamplifier, the NAC-N 172 XS introduces numerous innovative techniques for signal processing and isolation to ensure that each audio signal or stream is output with maximum fidelity. It employs a Burr Brown digital to analogue converter chip that offers the same performance as the one fitted to the NDX network player, and it benefits from all the filtering and signal management techniques that have brought Naim to the forefront of digital music in the home. 

NAC-N 172 XS component selection is entirely optimised for sound quality and the XS style case construction helps minimise microphony by providing a rigid, non-resonant foundation for the electronics. Like every Naim product, fastidious attention to power supply noise and regulation, PCB layout and earthing topology, is a fundamental element of NAC-N 172 XS performance. 

The result of all this extraordinary technology is extraordinary music reproduction that lives, breathes and satisfies. Integrate a NAC-N 172 XS in an existing audio system, or build a new pre/power amplifier system around it, and the world of high resolution audio, UPnP streaming, and the vast resource of internet radio can connect seamlessly with your existing world of CD and vinyl.
