Network Audio Players/Servers

Korea's Citech group continues apace with yet another 'full colour widescreen' offering from its HiFi Rose brand – this time with an updated network-attached media hub

ARose by any other name? As has happened in the past, Korean manufacturer HiFi Rose has launched a new version of an existing model – in this case its RS250 network player – with worthy specification changes and a suffix to set the two apart. But there's a mild inconsistency here, for when the company upgraded the RS150 [HFN Jun '21] to the current version, due to a DAC chip change forced upon the company by the 2020 fire at AKM's semiconductor plant in Japan, it became the RS150(B), selling for £3899, but the revised RS250 is now the £2349 RS250A, available in either silver or black finishes.

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…

This is not quite the most affordable of Lumin's network-attached players, but the D2 looks good, is sensibly priced and – thanks to a super-slick app – is a delight to use too

As the model number suggests, the £1845 Lumin D2 is the latest version of the company's affordable network audio player, the entry point for a range that started with the A1 back in 2012. And while the range has expanded, and some things have changed, much still seems the same: the D2 is compact, at just 30cm wide and a mere 6cm tall, and so light at 2.5kg that my stiffish Chord Company interconnects almost lifted it off its feet!
