Network Audio Players/Servers

Given Cambridge Audio's track record in digital audio, it is perhaps a little surprising it's taken the company so long to enter the network systems arena. It was an early developer of add-on DACs in 1994 [see HFN Jun '21] and has been making streaming components for a good while, even going to the lengths of developing its own network audio hardware. The Cambridge catalogue currently caters for 'computer audio' enthusiasts with the entry-level £169 DacMagic 100 right up to the £4499 Edge NQ network preamp.

There comes a time when you have to pop the champagne cork, relax and have fun. That’s what dCS (Data Conversion Systems Ltd) has done with its new £55k Vivaldi One single-box disc player/upsampling DAC/streamer. It’s a limited edition of just 250 pieces, designed to celebrate the company’s 30th anniversary. In that time, the company has gone from being an Official Secrets Act signatory supplying advanced radar systems for the RAF towards the end of the Cold War, to one of the most respected high-end digital audio specialists around.

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.

Oslo-based Hegel has been enjoying something of a purple patch of late: not content with raising eyebrows with the sheer performance of its flagship H590 integrated amplifier [HFN Oct '18], it went on to get dangerously near that level with the much more affordable H390 model [HFN Aug '19], offering almost all of big brother's sound quality for not much more than half the price. Our HFN review concluded that it was 'sensationally good value, with a clean, powerful sound and bags of musicality, not to mention exceptional flexibility including onboard network streaming'. Unsurprisingly, it won the 2019-20 EISA Award for 'Best High-End Amplifier'.

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…

The role of the hi-fi music server is changing. As we've noted in the past, what was once no more than an optimised NAS device, designed to feed an external network music player, has now become a complete storage playback solution, designed to connect straight to a USB DAC or, in some cases, with onboard digital-to-analogue conversion straight into an amp or preamp.
