Reviews

Exposure Electronics has added to the compact ‘XM’ series of hi-fi components it released earlier this year with a new preamplifier, the XM7.

‘The inspiration for the series came from the unstoppable resurgence of vinyl amid a digital age,’ said Exposure’s chief designer Tony Brady. ‘I see both formats as being here to stay and believe that both have further growth and development ahead of them. It’s no longer a case of either/or. At the same time, quality of sound is once again becoming important to an increasing number of people—across all media.

The new Exposure XM7 preamplifier includes a moving-magnet phono stage, a DAC with five digital inputs plus line-level inputs that include a fixed-gain input for home theatre use. There are two headphone outputs and two preamplifier outputs (to permit bi-amping.) Unlike many modern preamplifiers which use noisy switch-mode power supplies, the XM7’s supply is linear, and headed by a 200VA toroidal transformer.

Like other models in Exposure’s XM series, this new XM7 preamplifier is a smart solution for music lovers who want superior hi-fi performance but don’t want either the size or the cost of their system to spiral out of control,’ said Bill Plantzos, National Sales & Marketing Manager for RVM Australia, which distributes Exposure in Australia. ‘In short, in the XM series Exposure has somehow managed to offer its most extensive set of features yet, but in their smallest-ever component size and without compromising musical performance. So ‘less’ really is ‘more’.’
