Network Audio Players/Servers

A little over half the price of the mighty H590 amp, in a slimmer design and with very similar facilities and output, this new arrival from Norway is a sure-fire bargain

They're clearly fans of the old buckled swash at Hegel: having evoked Master And Commander in announcing its £9000 H590 flagship amplifier [HFN Oct '18], the Norwegian company says it's calling the new H390 'Robin Hood'. Why? Well, it's all a matter of re-distribution of wealth, apparently, for the £4900 debutant takes much of the ability of its big brother, and makes it available to those of us of humbler means.

The Norwegian brand’s latest amp is not just its most powerful integrated, but comes complete with network audio capability. Is this the ultimate one-box amp solution?

Obviously not afraid of a spot of (Russell?) crowing, Oslo-based Hegel describes its new Reference H590 integrated amp, just going on sale at £9000, as ‘Master and Commander’. Apparently it’s ‘A master at musicality’ and ‘The commander of any set of speakers’. Mind you, you might be tempted to forgive the company for its exuberance – after all, the new arrival is something of a monster, standing an AV-receiver-challenging 17.1cm tall, tipping the scales at 22kg and delivering over 300W per channel. Well, 301W a side actually, according to Hegel, making it at least 50% more powerful than its previous top integrated, the H360.

Korea's Citech group is ploughing its considerable in-house hardware and software resource into a series of network-attached players. Here's its most compact all-in-one

One of the great advantages offered by network-capable audio hardware is that, once a platform has been designed, it can be rolled out across a number of products, re-purposed and scaled depending on the target market. We've seen the same from brands as diverse as AVM [HFN Dec '21], Cambridge Audio [HFN Nov '21] and Naim [HFN Aug '21], and now recent arrival HiFi Rose is following the same path with high-end players designed to be used in existing systems all the way through to one-box soundbar set-ups.

Combining the network streaming capability of the RS150 flagship with the GAN-FET Class D amplification of the RS180, the RS520 aims to be the 'all-in-one' for everyone

Another smart move from the Korean tech specialist? That certainly seems to be the case with the latest arrival from Seoul-based HiFi Rose, which has rapidly established itself as a major player in the network audio/video market with a string of excellent streaming players. Having taken what looked like an abrupt turn with the launch of its bonkers-styled – but great-sounding – RA180 integrated amplifier [HFN Jul '22], it's now delivering on the promises made by the company's Sean Kim, interviewed for that review. We're yet to see the simpler, more affordable RA280 integrated amp, but here's the company's all-in-one streaming amp, the RS520.

Aiming high, this flagship two-box music server uses a separate, outboard linear power supply. But is this the perfect solution to all your music storage and playback needs?

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.

Krell announced at the 2014 Las Vegas CES its intention to introduce a UPnP/DLNA-compliant network media player and the rather aptly named Connect is now available in the UK. There are in fact two versions of Krell’s Connect player, the one featured here having an optional built-in DAC with balanced (XLR) and single-ended (RCA) analogue outputs. Needless to say it is vastly overbuilt compared with most music streamers! At its core lies a familiar BridgeCo-based StreamUnlimited platform including vTuner internet radio functionality. Massive power supplies have always been the cornerstone of Krell designs, and the Connect has an over-specified linear power supply with a 94VA toroidal transformer large enough to power a modest amplifier.

With multiple inputs, streaming functionality and plenty of power, this elegant and compact system promises consummate convenience and super sound. Does it deliver?

Since 1993, Lindemann has been making distinctive products, all with an accent on design and technology. Although the company has also sold loudspeakers in its 27-year history, electronics have formed the staple of the product portfolio – and it has shown a particular interest in digital technology. The D680 of 2001, for example, was the first German SACD player, while the original Musicbook was an early example of a highly advanced streaming front-end [HFN Jun '14]. Lindemann's thinking has been eerily prescient, as other brands have since scrambled to get similarly elegant so-called 'style systems' into their ranges…
