Astell & Kern AK380 Copper edition brings sonic benefits

The AK380 Copper edition is, as you've probably guessed by now, made from copper (a solid 1.7kg block to be precise), which is coated to prevent oxidisation.

Astell & Kern says copper results in “superior electrical conductivity and shielding performance”, and the company claims it has a different sound signature to the regular, duralumin-based AK380.

Max is a staff writer for What Hi-Fi?'s sister site, TechRadar, in Australia. But being the wonderful English guy he is, he helps out with content across a number of Future sites, including What Hi-Fi?. It wouldn't be his first exposure to the world of all things hi-fi and home cinema, as his first role in technology journalism was with What Hi-Fi? in the UK. Clearly he pined to return after making the move to Australia and the team have welcomed him back with arms wide open.
