Exposure XM7 Pre-Amplifier

The XM7 is a compact but well featured pre amplifier that includes an MM Phono input, 1 line level input, 1 fixed level input (AV), a USB and 2 coaxial (BNC) and lastly 2 Optical inputs.

There are two pre amp outputs along with a 3.5mm and a 6.35mm headphone outputs (both mounted on the rear panel along with the switch to choose between using either the headphones or the pre amp outputs).

To top it all off there's a remote control, making this a very space efficient high quality pre amplifier that follows Exposures philosophy of using a very substantial power supply based around a large (200va) toroidal transformer along with discrete devices for its output stage.
