The NDS is an audiophile source, capable of playing and streaming audio over a home network at up to 24bit/192kHz resolution. It offers internet radio yet forgoes a DAB and FM radio tuner to minimise noise. It includes three S/PDIF digital inputs for connection to external digital sources, such as a computer or CD player. A front-panel USB port complets the feature set – either connect an iPhone or iPod digitally to allow the NDS to control and play stored audio or play audio from a USB memory stick, even hi-resolution WAV or FLAC files, with full on-screen control. The NDS will support all the main file formats. WAV, FLAC, AIFF, ALAC, AAC, Windows Media-formatted content, Ogg Vorbis and MP3 files are all catered for, as is gapless playback.
In true Naim reference engineering style, the NDS requires the use of an external power supply. The XP5 XS, XPS and 555 PS are all suitable matches. Performance can be further enhanced by the addition of a second Burndy cable (in the case of 555 PS only) splitting out the analogue and digital sections, which a second 555 PS will bring about even greater gains.
Like its fellow network players, the NDS can be controlled by Naim’s n-Stream control app for iPad, iPhone and iPod Touch. The app also alows control of a Naim system’s inputs and volume. The supplied remote and front-panel interface provide simple and easily accessed control.
