Headphones

With modern smartphones able to offer high-resolution audio playback, the market for dedicated portable audio players is now fairly niche. One of the biggest fish in this relatively small pond is Astell&Kern, which offers an extensive range of models priced between £625 and £3400. These are divided into four lines – KANN, A&norma, A&futura and A&ultima – with the £1099 KANN Alpha being the latest addition to the KANN series and slotting in between the existing KANN and KANN Cube players on price.

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.

Writing in his Welcome page last month, editor Paul Miller explained how shifting hugely heavy equipment about is all part and parcel of the HFN reviewing 'experience'. Perhaps he was eyeing a recent speaker launch proudly declaring that its new products weigh over 450kg apiece. Add on their external crossover with its power supply, and a quartet of high-quality amps to drive them, and you could well end up wondering whether your floor will support a tonne and a half of hi-fi.

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].

If you're looking at the photos of the Aeon 2 here thinking, 'Isn't that a MrSpeakers product?', the answer is yes and no. The original Aeon was indeed made by MrSpeakers but recently the company changed its name to Dan Clark Audio, Dan Clark being the company founder. It was a sensible move because MrSpeakers had never made, or looked like making, a loudspeaker, but like all company name changes it can take time to bed in.

When we reviewed the LCD-2 [HFN Mar '13], Audeze was in the vanguard of what was to become the rebirth of isodynamic driver technology, more commonly known today as 'planar magnetic'. To those of us who'd lived through the high-profile launch of the original PM headphone, the futuristic looking Wharfedale Isodynamic, 40 years earlier, it came as a surprise.

When it comes to affordable music players with hard disk storage, few companies have the pedigree of Korea-based Novatron. Its range of products, sold under the Cocktail Audio brand worldwide – including here, before a UK-only rebranding to Novafidelity – starts from as little as £650 for the X14 model. In this instance the user is able to decide how much storage capacity to have installed, or even buy the unit 'bare bones' and add their own choice of drive.
