Outboard DACs

Korea’s HiFi Rose launches its second-generation streamer/DAC flagship with onboard storage facility, more powerful DSP, improved connectivity and Full HD touchscreen

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..

A simple but effective USB DAC solution. When circumventing a computer’s low quality internal audio processing and pushing out digital audio to an external DAC, there’s nothing more convenient to use than something like the USB-powered Streamer II+ from Californian company High Resolution Technologies (HRT). This is especially true when you consider that the unit boasts asynchronous USB inputs.

Matching the power of the iDSD Diablo 2 but with 4x the battery capacity and a host of new processing features, the iDSD Valkyrie is set to storm your portable listening 


Swooping down into iFi Audio’s ever-expanding line-up, the £1699 iDSD Valkyrie stakes its claim as the new flagship portable. The brand typically excels at offering oodles of functionality at very reasonable prices, although the £3749 iCAN Phantom desktop headphone amp [HFN Sep ’23] shows it also has form when it comes to high-end head-fi. Nevertheless, and despite boasting a lot of familiar iFi Audio features and technologies, the iDSD Valkyrie is a very different beast – not least because it boasts a gargantuan 20,000mAh battery for extended mobile use.

Launched with a typically dazzling array of acronyms, the NEO iDSD is nonetheless a more focused DAC/pre/headphone amp, equipped with the latest 'hi-res' Bluetooth

Seemingly there's no stopping Southport-based iFi Audio: it just keeps on trotting out new digital products, all aiming to fill a gap in the market – or create a new gap to fill. Indeed, while writing this review I was unsurprised to see another new launch pop up, in the form of the bright red iDSD Diablo.

The most ambitious iFi digital product to date is a hugely flexible DAC/headphone amp with an eye on both studio and consumer markets. But is it just a bit too complex?

The idea of the DAC/headphone amplifier is firmly established, whether for ‘on the go’ use, desktop audio or as a main system component. Less than £100 will get you started, with the likes of the AudioQuest DragonFly Black [HFN Oct ’16], Cambridge Audio DacMagic XS V2 or Cyrus SoundKey, while the ambitious might consider models such as the long-running Chord Electronics Hugo [v2, HFN Aug ’18] and costing the thick part of £2000. However, even by the standards of this highly diversified market sector, the range-topping model from iFi Audio, the Pro iDSD, looks pretty punchy with its £2500 price-tag.

With a more compact and elegant design, plus both wired and wireless connectivity, iFi Audio’s new top-of-the-range portable DAC/headphone amp seems to have it all

The iFi Audio range of portable DACs and headphone amps has been one of the main challengers to the popular Chord Mojo [HFN Jan ’16], with its first-generation nano iDSD [HFN Dec ’14] picking up an EISA Award back in 2014. The company recently updated its range with the entry-level nano iDSD Black Label [HFN Apr ’18], which offers a highly competitive audio upgrade for just £199. However, it’s this new xDSD model that’s setting the standard for the company’s latest range of products, with a more streamlined and portable design, improved connectivity, and a £399 price tag that pits it right up against the Mojo.

With its eye-catching looks, flexibility, solid engineering within and a remarkably grown-up sound, this entry-level DAC from iFi Audio is a conspicuous hi-fi bargain

We've come a long way since iFi Audio was started as an offshoot of high-end brand Abbingdon Music Research, building its initial reputation with its 'Purifier' products, designed to clean up digital signals. And if anyone was labouring under the delusion that these were devices designed to tackle non-existent problems – you know, the old 'digits is digits' thing – the company has since expanded into making everything from complete systems to some of the most cost-effective DACs and headphone amps around. After all, its excellent xDSD [HFN Jul '18], was a 2018-19 EISA Award-winner, following on from the 2014-15 winning footsteps of the nano iDSD [HFN Dec '14].
