Exposure XM HP Headphone Amplifier

The XM HP is an incredibly well specified headphone amplifier. It is really a full pre amplifier and headphone amplifier combined. Its long feature list includes a Moving Magnet phono stage, two line level inputs, two coaxial digital (BNC), two optical and a USB, along with a pre amplifier output and fixed level output. A remote control is also supplied of course.

Headphone outputs include two 6.35mm and two XLRs and there's ample power meaning that two pairs of headphones can be driven at the same time.

The XM HP is ideal for anyone that needs either a high performance headphone amplifier or a very well featured compact pre amplifier - it's a real swiss army knife of a product!
