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?'.

Arriving to crown Audiolab's top-flight 9000 series, which launched with the 9000A integrated amplifier and 9000CDT CD transport [HFN Aug '23], the 9000N is arguably the most intriguing model in the range. This streaming DAC, priced at £2499, and styled to match, marks a point of departure for the brand as its association with DTS Play-Fi is cut in favour of a new streaming platform and app.

We've commented previously on the similarity – at least in styling – between many of the products in the Auralic range, and here's another head-scratcher in the form of the Altair G2.1. It's only a little more than the Aries G2.1 'Wireless Streaming Transporter' [HFN Feb '21] – £4599 plays £4199 – yet this model, designated a 'Digital Audio Streamer', is a much more comprehensive product. It comes complete with onboard DAC, a preamp that allows it to drive a power amp or a pair of active speakers directly, and there are even analogue inputs – a line level and MM phono – to reinforce that role as a complete system hub.

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.

At Munich's High End show in May 2023, a rare appearance by Auralic founder Xuanqian Wang heralded the launch of G3 versions of its Aries streaming transport and Vega streaming DAC, destined to extend the company's reach into the high-end when they arrive later this year. Yet at the same event the digital audio specialist introduced new G2.2 iterations of the Aries (tested here) and Vega [HFN Nov '23], both now available priced £5299 and £6899, respectively. Somewhat confusingly, all four models – regardless of their generation number – use the same G3 version of Auralic's Tesla streaming platform.
