Network Audio Players/Servers

There are times when one might think Kent-based Chord Electronics is being wilfully abstruse in its selection of model designations. After all, its flagship DAC is called DAVE [HFN Apr '16], and its pocket-sized DAC/player combination is the Mojo [HFN Jan '16] and Poly. Then there's the portable Hugo DAC/headphone amp, now in both Hugo 2 [HFN Aug '18] and less-portable Hugo TT (for 'tabletop') versions [HFN Dec '15], to which the company has now added two extra units, named 2go and 2yu.

There are two ways to make a network music player. One is to take a streaming platform and integrate a DAC to provide analogue outputs, while the other is to start with a DAC and then build in the network playback capability. The two approaches have their strengths and weaknesses. Typically, the network player with DAC will be just what it says: a full-featured machine, usually complete with a display, but with limited connectivity for external digital sources. The DAC with streaming, meanwhile, will commonly have more digital ins, but sometimes less network audio capability.

There's so much functionality under the bonnet of Bryston's BR-20 that you might wonder where to start. I would suggest the manual – this £7500 networked USB DAC/preamplifier isn't, it must be said, the most instantly intuitive of system hubs I've ever auditioned. But the effort is worth it though, because what the BR-20 can do, and how it does it, is quite special.

One of the great benefits of the rise of streaming – be it network or online – is the flexibility it gives manufacturers to create just about any product they like. There are some basic formats, including the all-in-ones like the Naim Uniti [HFN Nov '17], NAD M-Series [HFN Aug '20] and the new Cambridge Audio Evo. There are also streaming amps and standalone playback components (network players or DACs), but within those parameters the engineers and designers have no shortage of freedom to create network audio devices in just about any shape they want…

Once upon a time there was just Astell&Kern, the company building its reputation on superior digital audio players (or DAPs) aimed at those for whom playing music from their phone just wasn't enough. In an era when the multifunctional pocket device is designed to take over every task you could imagine, from browser, emailer, camera, music player and – well – phone, the idea of carrying a dedicated audio device around may seem like something of an anachronism. 'An MP3 player, grandad?'.

Based in Xi'an, the ancient city in northwest China that's home to the famous Terracotta Warriors, Matrix Audio has a classic hi-fi backstory: it was founded by three audio/music enthusiast schoolmates who regrouped some years later to launch a company to develop and produce hi-fi separates. The DA-100plus DAC was its inaugural product in 2006 since which time the company has evolved its lineup to encompass a range of digital and streaming products that covers just about all the bases, from the X-Sabre Pro DAC [HFN Nov '17] to the new £2795 Element X.

The continued rise of network audio has created a new game in the hi-fi world, best summed up as 'Yes, but what is it?'. You see, all sorts of network-capable devices exist right now, and it seems each of them has a somewhat different approach. For example, perhaps the best-known name in 'audiophile servers' or 'music libraries', Melco, started out by making products designed to feed network players over a network connection, paying close attention to the isolation and optimisation of the Ethernet feed. It then reinvented itself as a maker of network transports, connecting directly to a suitable DAC using a USB output, again with isolation strategies implemented.
