Astell&Kern claims that the stainless steel build is not just for sturdiness and aesthetic design, it has audio properties too. "By offering more ground points, the AK240 Stainless Steel edition eliminates more electrical 'noise', meaning a purer audio experience," said the manufacturer.

"The standard AK240 already has laser-etched ground points on its anodised duralumin body, but with the Stainless Steel edition the entire casing acts as grounding."

The limited edition AK240 will be available through
