Headphones

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.

Veteran makers of headphone amplifiers for studios, Manley Laboratories is taking on the extreme high-end of the domestic genre with a £4500 unit – the Absolute – that marries audiophiles' sonic requirements with the total control demanded of professionals. Company CEO Eveanna Manley says, bluntly, 'Our goal was simply to produce the most awesome-sounding and sonically flexible vacuum tube headphone amplifier!'.

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.

Imagine that instead of each of your stereo loudspeakers sitting in splendid isolation, optimally aligned with respect to the listening seat, there was a large band of metal or plastic curving between them, joining the two cabinets. If you know anything of loudspeaker design and the efforts taken to quell structural resonances, you'd immediately suspect this structure of colouring the sound and – by carrying vibrations from one speaker to the another – of messing with the stereo image.

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.

Time flies when you're having fun. I bought the equipment to measure headphones for Hi-Fi News as long ago as May 2007, since when I've tested around 115 different models for the magazine. These have included circumaural (over-ear) designs, supra-aural (on-ear) and insert, active and passive, priced from under £100 to almost £5000.

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.
