naim nac-n 172xs


The NAC-N 172 XS is a network player and preamplifier in one. It only needs to be paired with a power amplifier to form a neat two-box solution offering separate pre and power amplification along with integrated digital sources: UPnPTM network streaming, internet radio (optional FM/DAB), playback from iPod/MP3/USB and five S/PDIF inputs.

When controlled with the Naim n-Stream app, system automation can be enabled giving full control of all connected Naim sources.
