Cambridge Audio is ready to rock this week’s CES 2015 with one little box. Yes, it’s small, but the Azur 851N Network Music Player packs quite a wallop.

That’s because the latest in the company’s Azur 851 Series can deliver awesome sound from just about any digital format you throw at (through?) it. It can even please your inner-audiophile, since it supports up to 24-bit/192kHz studio master quality files. The new flagship network music player can also upsample incoming audio to 24-bit/384kHz.

Designed to play nicely with just about every digital audio source, the 851N can be wired or connected wirelessly via UPnP over a home network to tap into music stored on computers, laptops and NAS drives. It even has three USB inputs for direct playback from USB HDDs and memory sticks. Other connectivity options include two TOSLINK optical inputs, two S/PDIF coaxial inputs, an AES/EBU input and asynchronous USB audio. Also worth mentioning is that the 851N has RCA and balanced XLR analog outputs, as well as a digital AES/EBU, TOSLINK and coaxial outputs, and a RS-232 port.

That asynchronous USB audio means that this slim component can also play 24-bit/192kHz audio files from a computer or laptop, with the 851N acting as an external sound card. Read More
