hfnoutstandingIt's a brave company that launches a £20,000 headphone as only its second product – and an electrostatic too. Yet more remarkable: that company isn't Chinese but British!

Electrostatic headphones are like royalty: rarefied enough to assume an aura that rivets mass attention. In the case of Warwick Acoustics' Aperio, it's not just its operating principle that catches the eye and sparks interest but its price too: at £20,000 this isn't the most expensive headphone/amplifier combination ever seen but it's up there with the very few daring to dangle a price tag greater than that of a family car.

hfnoutstandingBeryllium drivers, sustainable hardwood, real leathers, price – these debut open-back 'phones tick all the boxes. But do they offer the ultimate in sound quality?

Mention beryllium and digit counters begin to whorl in the imagination. Unquestionably the very best metal from which to construct a headphone or loudspeaker diaphragm – because the speed of sound through it is over twice that of aluminium, magnesium or titanium – its use has historically been constrained for two reasons.

hfnedchoiceThe Chinese company claims a decade of planar driver technology development with these robust mid-priced open-backed 'phones – are they a cause for celebration?

With HiFiMan's UK distribution now switching to Signature Systems, we are at last able to get our hands on this idiosyncratic range of headphones from China. What makes them idiosyncratic is not merely their use of planar magnetic (aka isodynamic) drive units – something which is becoming increasingly mainstream – but that these drivers are reminiscent of isodynamic units of the past in respect of their low sensitivity.

hfnoutstandingThe French speaker company has upped its game with this de-luxe closed-back design – perhaps aimed to make a 'mocha-ry' of the competition? Let's see how well it sounds

Hot on the heels of the Elegia [HFN Mar '19] – the first closed-back model in Focal's revamped, post-Spirit headphone range [HFN Dec '15] that launched in 2016 with the open-back Utopia [HFN Feb '17] – comes the second closed-back design, the £2799 Stellia. These two flagship models, both featuring beryllium diaphragms, effectively bookend the range, their less costly siblings being based around the same M-cone drive unit concept but with a less exotic aluminium-magnesium diaphragm.

hfncommendedA development of the earlier M4U 2, this new design adds Bluetooth and internal battery charging while listening, via micro USB. How do the improvements stack up?

Although it received a lukewarm review in these pages [HFN Dec '13], the M4U 2 – predecessor to the M4U 8 we're looking at here and still available – proved to be a success for PSB, garnering plaudits and awards along the way. The M4U 8 looks very similar and it would be easy to suppose that it's just an M4U 2 with wireless capability in the form of Bluetooth and NFC (near-field communication) bolted on. In fact it's a bit more than that, principally because its onboard DSP capability allows it, in active mode, to deliver a more precise adherence to PSB's RoomFeel target frequency response.

hfncommendedShort of having a dedicated generator in your garage, you are not going to get cleaner mains than from PS Audio's new Power Plant, which is bigger and better than ever

In a game of audiophile word association, 'mains regenerator' will elicit the response 'PS Audio' just as surely as 'electrostatic headphones' does 'Stax'. PS Audio can't claim to have introduced mains regeneration to high-quality sound reproduction – that distinction belongs to Linn Products and the Valhalla board for the LP12, introduced in 1982. But nobody generalised on that specific, realising that a regenerated mains waveform might bring improvements to audio components other than a turntable's synchronous AC motor, until PS Audio introduced its original Power Plant, to a somewhat bemused hi-fi industry, in 1998.

hfnoutstanding.pngIf you've admired Vivid Audio's design philosophy but baulked at its styling, the new Kaya range is for you

Audiophiles can be a conservative bunch. Me, I sometimes feel that if I ever see another wood veneered box loudspeaker I'll attack it with a chainsaw but others of you, I know, prefer the old aesthetic, or at least a modern take on it, to curved, organic cabinet forms – especially if painted in primary colours. For a company like Vivid Audio, which appreciates and exploits the benefits of curved cabinets in respect of structural stiffness and clean diffraction behaviour, this is a problem.

hfnoutstanding.pngIf the BeoLab 90 wowed you with its tech but daunted you with its size and price, here’s a pint-sized alternative

Kii Audio’s THREE is an exemplar of what can be achieved when the hi-fi industry’s, and hi-fi buyers’, lingering obsession with passive loudspeakers is set aside and a 21st century approach – active operation in conjunction with digital signal processing (DSP) – is adopted instead. In short order we’ve experienced the B&O BeoLab 90 [HFN Dec ’16], the KEF LS50 Wireless [HFN Oct ’17] and now the Kii (pronounced ‘key’) THREE.

hfncommended.pngFollowing a succession of top Audio-Technica headphones that were variations on a familiar theme, this latest flagship open-back model rings some significant changes

Audio-Technica currently offers a bewildering 22 headphone models to its European customers in the hi-fi category alone, and goodness knows what exotica there may be which never escapes Japan. Prices range from £30 at the bottom end to £1990 at the top, that latter tag dangling from this new model, the ATH-ADX5000, but if you thought you knew what to expect from A-T’s most expensive headphones, it may surprise you a little.

hfncommended.pngAn engineering tour-de-force informed by the latest research in ‘targeted sound curves’, the miniature N5005 in-ear headphone features no fewer than five drivers

The hi-fi industry throws up some wonderful contradictions. If this were a review of a five-way loudspeaker you’d expect it to be a monster and question whether five-way wasn’t one way too many. If the subject of the review were a five-way over-ear headphone you’d think the world had gone mad: most over-ear headphones make do with a single drive unit, and while there have been two-way models they have rarely been successful. Yet going down the size scale one more notch to the insert earphone (aka in-ear headphone), here we have a new £800 flagship model from AKG boasting, yes, five drive units within its compact exterior dimensions.
