EXPOSURE XM HP HEADPHONE AMPLIFIER
Exposure Electronics has added an ‘HP’ headphone amplifier to its small half-width chassis XM series. The new Exposure XM HP headphone amplifier is not just a headphone amplifier, because it also includes a moving-magnet phono stage, two line inputs and a digital-to-analogue converter with four SPDIF digital inputs and one USB input.
As with all other components in the XM series, Exposure’s chief designer, Tony Brady, has opted for a linear rather than a switchmode power supply. The supply in the XM HP has a 60VA custommade toroidal power transformer. The headphone circuitry is entirely discrete, with Brady saying that he’s ensured it has a sufficiently high current capability to drive low-impedance headphones. The circuit can drive two pairs of headphones simultaneously, via two pairs of 6.35mm jacks or two pairs of XLR jacks. Other models in the Exposure half-width XM series include the XM3 phono stage, XM5 integrated amp, XM7 preamp and XM9 mono power amplifiers. In the UK, the Exposure XM HP Headphone Amplifier retails for £1,299. For more information please contact Exposure’s Australian distributor, RVM Australia on (08) 9417 9944 or visit www.rvm.com.au
