Network Audio Players/Servers

If Apple’s now-discontinued iPod is the spiritual forebear of all portable digital players, what’s available on the market in 2026 has progressed light years beyond Jony Ive’s original. This new flagship model from Korean brand Astell&Kern is also portable – but its size and 651g weight won’t see you casually sliding it into a coat pocket. The £3799 price tag might make you think twice about brandishing the SP4000 while commuting on the Tube, in any case...

In the wake of well-established products such as the Sonos Amp and Bluesound’s Powernode, we’ve seen a slew of compact all-in-one amplifiers from brands including Denon, Marantz [HFN Aug ’24] and WiiM [HFN Nov ’24]. Now Chinese company Eversolo enters the fray with an offering that, while not the most affordable of its ilk, is keenly priced if you consider its extensive list of features. The Eversolo Play, at £599, even boasts a touchscreen displaying the Android-based interface also found on the brand’s DMP-A10 [HFN May ’25] and DMP-A8 [HFN May ’24] streaming DAC/preamps.

To misquote those old M&S adverts, this isn’t just a network streamer, this is the HiFi Rose RS451 Master Fidelity Network Streamer. The latest addition to the Korean company’s ever-expanding digital audio offering, it features second-generation technology trickled down from the high-end RS151 [HFN Jul ’25] launched earlier this year. This makes it, in HiFi Rose’s terms, ‘a semi-reference level network streamer’.

Back in the day, when CD players started splitting into separate transports and DACs, the question was ‘does the transport really make a difference?’. After all, we all knew that different DACs had their own influence on the sound – despite the protestations of the ‘all properly designed digital gear should sound the same’ brigade – but transports? Their sole purpose was to deliver digital data from disc to DAC.

Although the Paris-based audio brand, Devialet, debuted with its groundbreaking D Premier integrated amplifier in 2010 [HFN Apr ’10], it’s arguable that its most well-known release has been the Phantom [HFN Feb ’15]. Launched in 2015, this almost spherical-shaped active, wireless speaker leveraged the brand’s electronics knowhow and eye for a smart aesthetic to shake up the compact hi-fi market. Upgraded models have appeared in the decade since, but only now does the manufacturer feel confident in launching a new ‘Ultimate’ edition.

On recent form, the £13,500 dCS Lina DAC X could almost be considered ‘conventional’. Following on the heels of the Lina headphone amp system [HFN Nov ’22], and the massive – and massively pricey – multibox Varèse player [HFN Feb ’25], complete with separate mono DACs and the option of an SACD/CD transport add-on, the Lina DAC X looks dangerously like any number of models from rival companies, from its proportions to the inclusion of a front-panel rotary volume.

A rose by any other name is still a HiFi Rose? Well yes, it can appear that way: since it first arrived on the hi-fi scene, the Korean company has launched a head-spinning barrage of products, all of which can, at first glance, look rather similar. However, what’s been going on is a policy of expanding the appeal of the range upwards, downwards and outwards – the last, for example, by adding its own lineup of amplifiers – and introducing a programme of upgrades along the way..
