Astell & Kern has launched a limited Copper edition of its AK380 flagship high-resolution portable music player, and it is stunning. Milled from a 1.7kg hunk of solid copper, laser etched, hand finished and coated to prevent oxidation, it also boasts a carbon-fibre backing and sumptuous leather case. It also plays music spectacularly well. Capable of handling 32-bit/384kHz playback from virtually any format or file, the AK380 is a hi-res dream. And don’t think for a second that the use of all that copper is just really, really cool, Astell & Kern believes the conductive properties deliver a completely new sound signature compared to the duralumin-based AK380.
