Network Audio Players/Servers

Network audio is a significant growth area in hi-fi, helped along by network-connected transports and servers, designed to be used into offboard DACs. We used to call these devices 'network bridges', interposed between the home network, and any storage devices thereon, and an audio system. Nowadays they've grown beyond that basic functionality, being able to access music stored internally or via directly connected drives. Meanwhile, the 'network connectivity' is used to access online streaming services, and offer remote control via a tablet or smartphone app.

CD players, along with integrated amps, have long been such a mainstay of the Arcam product catalogue that it comes as something of a surprise that the CDS50 we have here, selling for £699, is now the sole silver disc spinner in its lineup. This, after all, was the company responsible, in 1986, for the first CD player both designed and manufactured in the UK, just four years after the format hit the shops and at a time when Linn and Naim were both sticking to their 'no good will come of this' guns.

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?'.

Although Auralic (promoted as AURALiC) only launched the Altair G1 in 2020, the Chinese brand already has its G1.1 update available. It appears together with the Aries G1.1 as the new and more affordable options within their respective tiers, with the Altair and Aries G2.1 [HFN Oct '21 & Feb '21] being the more expensive models. However, as all Auralic products share a very similar chassis design and carry names that aren't very descriptive, it's sometimes difficult to discern which box does what.

Yes, the £2699 Aries G1.1 is another one of those similar-looking Auralic components that will blend seamlessly with its brand partners, even if we're never immediately sure what box does what... In this case, we have a network player without onboard digital-to-analogue conversion, designed to be used straight into an external DAC. In this guise, it brings the niceties of Auralic's Lightning Streaming Platform, and its Lightning DS control app, to owners of third-party DACs. This also includes amps or preamps with digital inputs, which can be fed via USB or optical, coax or AES.

For many hi-fi enthusiasts, the idea of 'computer music' is still an alien one, not least because what's claimed to be a simple way of accessing music can seem to be extremely complex. After all, unless you're going to listen to everything via online streaming you need a means of ripping your existing discs, a way to tidy up the metadata tags used as signposts for indexing and search, and of course somewhere to store all the music files. And that's before you even think about how to play it.

Look at any multi-box component and you can usually work out what's going on: CD transport and DAC, preamp and power amp(s), for example. But just as often those two boxes are an 'audio product' – phono preamp, headphone amp, DAC or even a digital audio transport – plus an outboard power supply. The rationale for these latter two-boxers is clear, for by isolating the electrically noisy parts of the system away from delicate audio signals, interference is minimised and signal purity maximised.
