Exposure XM7 Pre Amplifier
Presented within a narrow, half-width design, the new XM7 preamplifier includes a built-in moving magnet phonostage and DAC which sports five digital inputs. There’s also a fixed gain home theatre input and two headphone outputs. Two preamp outputs allow for bi-amping. Spanning 218 x 89 x 363mm, it weighs 4.8kg.
