Astell & Kern has launched a copper-clad spin on its high-end SP4000 portable music player.
The new SP4000 Copper is teased as a "range-topping addition" to the brand's extensive arsenal of digital audio players, bringing together precision engineering and a 99.98 per cent pure copper exterior to bring the established SP4000 flagship player to a new level of audio performance.
This isn't the first time we've seen the Korean company send one of its portable players out to battle in shiny copper armour – the former AK380 flagship from around ten years ago also enjoyed a 'Copper' edition as an alternative to the duralumin-based standard model.
The addition of copper, however, promises to take take the player's performance to "another level". A&K claims the metal displays "ideal audio properties" which directly shapes the SP4000's sonic character, with copper's natural conductivity and shielding properties helping to preserve your music's finer details.
Says Astell & Kern, the SP4000 Copper delivers "deep, authoritative bass, a rich and articulate midrange" complimented by a "treble that decays with natural ease" thanks to its unique metal cladding.
The new model shares the same feature set as the standard SP4000, including support for the high-quality aptX Adaptive and LDAC Bluetooth codecs for 24-bit audio playback, as well as around 10 hours of continuous playback from a single charge.
The limited edition A&ultima SP4000 Copper is available now, priced at £3999 / $4499 / €4699. That's a modest advance on the £3799 / $3900 / €4499 for the standard iteration of the flagship player.
