Network Audio Players/Servers

Packed with proprietary technology, this network bridge is the obvious partner for Aqua's own DACs. But does its appeal extend beyond a one-brand digital set-up?

Never let it be said that AQ Technologies is either a follower of fashion or a taker of the easy route: the Milan-based company behind the Aqua range always does things its own way. And while that might sometimes seem like an exercise in making life difficult for itself, the policy typically pays off in the performance, as we discovered when reviewing the Aqua Formula xHD Optologic DAC [HFN Apr '20]. Under the Nextel-finished anti-resonant aluminium casework of that model – one of three DACs in a total Aqua lineup of five products – is a galvanically-isolated resistor-ladder converter of novel design.

Arcam's flagship integrated amplifier combines Class G amplification with features including network streaming, AirPlay 2 and offboard Dirac Live room correction EQ

Arcam is still headquartered in Cambridge, from where it took its original name, but the audiophile marque is now part of Samsung's global consumer electronics empire, through the latter's acquisition of Harman International, which had added Arcam to its portfolio in 2016. And amid these management-level changes, Arcam's product line has also undergone a refresh. The brand has withdrawn, for the time being, from the peripherals market, jettisoning its R series of docks and DACs.

With powerful battery pack and styling inspired by the Mars rover, the CA1000 aims to squeeze the performance of a full-sized 'digital' headphone amp into a portable player

The new Astell&Kern ACRO CA1000 desktop player/DAC/headphone amplifier, selling for £1999, has a raft of functionality built-in – and yet I'm still not quite sure who it's for… Of course, this is far from the first step beyond its core expertise in high-quality pocket music players taken by the company. After all, it's already given us the extraordinary AK500 stack system [HFN Apr '15], active speakers and the chunky ACRO L1000, its first desktop headphone amp/DAC.

Built as a 'box within a box', and promising a slicker all-round performance, Auralic's G2.1 series now extends to the fully-fledged Altair streaming DAC/preamplifier

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.

This high-end digital music machine is a comprehensive package offering ripping, storage, streaming and a built-in DAC. Is Aurender's flagship player master of all?

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.

The first in a new breed of ‘computer transports’, WideaLab’s Aurender S10 employs a Linux-based OS and solid-state storage to render your music collection via digital outs. Aurender music servers are new to the UK. Made by WideaLab, a specialist subdivision of Korea’s Wonik Corporation, they are designed for pure audio replay of a lossless digital music library – aimed squarely at audiophiles who care passionately about sound quality. That’ll be us, then!

The latest all-in-one compact Class D streaming system from the German company features an enhanced network audio platform – but that's only the start of its appeal

As the model designation suggests, this isn't the first all-in-one network audio system from German high-end company AVM. Replacing its existing Inspiration CS 2.2 model, the new Inspiration CS 2.3, selling for £5250 in black or silver finishes, with a chrome 'Cellini' finish available as a somewhat glitzy extra-cost option, is based around the company's latest streaming platform.
