Network Audio Players/Servers

With the H600’s streaming/DAC platform at its heart the new H400 – dubbed the ‘Streamliner’ by Hegel – looks set to take over as the sweet spot of the range

When Hegel’s reference H600 integrated amplifier [HFN Oct ’23] arrived to replace the H590 [HFN Oct ’18] last summer, it didn’t require much insight into the hi-fi industry to guess that the H390 [HFN Aug ’19] would also be marching in the general direction of the exit soon enough. It’s taken a year, though, before the replacement H400 – aka the ‘Streamliner’ – eventually pulled into port.

The new entry-level model in the Norwegian company's amp range is a sensible mix of facilities and performance – or at least it would be, if the sound wasn't sensational!

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'.

Korea's HiFi Rose has moved upmarket with its first DAC-less, transport-only network player – the result is an impressive combination of purity and innovative technology

As if on a one-company mission to prove all the variations possible when it comes to network audio, Korean brand HiFi Rose has gone in very short order from being an upstart newcomer to its current role as a pillar of the digital establishment. And it's done so not by the simple expedient of taking one platform and pitching it at a range of price-points, but rather by expanding its offering to fill every niche from the all-in-one 'just add speakers' system [HFN Mar '22] to the highly-focused high-end network component explored on these pages.

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.
