Exposure Electronics has added an ‘HP’ headphone amplifier to its XM series, all of which have small half-width chassis just 218mm wide and 89mm high.

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 a 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 switch-mode power supply. The supply in the XM HP has a 60VA custom-made 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 XM series include the XM7 Preamplifier, XM5 integrated amp, and XM9 mono power amplifiers.
