Network Audio Players/Servers

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 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 The brand has withdrawn, for the time being, from the peripherals market, jettisoning its R series of docks and DACs.

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.

At first glance, Chinese company Auralic's range looks baffling, such is the choice of similar-looking units – and it's becoming more so with the arrival of new 'second generation' G2 models, confusingly distinguished by the addition of a '.1' suffix on its product designations. In the new lineup there's the Vega G2.1 streaming DAC, at £5999, the Sirius G2.1 upsampling processor at the same price, the £7999 Leo GX.1 master reference clock, and the product we have here, the £4199 Aries G2.1, described as a 'Wireless Streaming Transporter'.

Music storage: it can be a thorny subject, not least because those network products offering internal capacity for your library tend either to have fixed, non-expandable storage, or offer the option of dealer-installed drives. The cost of such storage is usually high, too – okay, not 'adding capacity at time of ordering your new Apple computer high', where an extra Terabyte can cost you £400, but still at prices to have you looking at HDDs on the likes of Amazon and scratching your head.

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.

With its upgraded M1 Dual Mono DAC now in 'Classic' form and selling in the UK at £9499, Bricasti has also announced a more affordable alternative, but still offering 'an incredible array of performance'. The basic M3 USB DAC is offered at £5399, but this increases to £6999 when fitted with its DNLA/UPnP-compatible network streaming card and new headphone amplifier option. The latter includes both 4-pin balanced XLR and 6.35mm single-ended jack outputs, and is available as a return-to-factory retro-fit option as the front fascia requires some reworking.
