Naim Audio NACN172XS

Naim nac-n172xs


Other than it’s name being a bit of a mouthful, this is an extraordinary and much overlooked product. It is far more than just a streamer.



The above picture gives a bit of a clue to the true nature of the 172. Basically it is a pre-amp, a DAC as well as a streaming audio player. Match this wondrous product with a power amplifier or active loudspeakers and you have a simple and yet superb audio system.

There are two analogue inputs, 4 digital inputs and a fixed output, as well as line AND din outputs to enable use of any good power amplifier (as well as Naim’s own units). So you can connect a turntable, as well as things like Sky boxed and TV’s. Of course you can also connect your i-device via the standard charge cable. It will play music and charge the device.

The 172 can be partnered with any of Naim’s power amps including the matching 155XS. But don’t think it isn’t happy with better power amplifiers than the matching slimline one. Because of inherent simplicity of the design and the quality of the volume control this unit will happily partner more expensive power amps. We’ve actually a few customers who are using these with the NAP-250.

A higher performance version also exists; the NACN272.
