Astell&Kern SP4000

The Astell&Kern SP4000 is a milestone in high-end digital audio reproduction. Thanks to its innovative octa-audio circuit architecture, the SP4000 achieves unrivalled precision and clarity of sound. Signal processing with four advanced AK4191 digital processors and four AK4499EX DACs enables accurate signal transmission with drastically reduced noise components. ESA (Enhanced Signal Alignment) technology ensures flawless frequency coherence, so that even the finest nuances are reproduced in detail. The high-driving mode helps the SP4000 to deliver powerful, stable output power and create a sound image that is both dynamic and rich in detail. The SP4000 is the first Astell&Kern player with a full Android operating system. Any apps such as Tidal, Qobuz, Spotify or Apple Music can be installed and used quickly and easily. The ultra-low noise LDO regulation reduces the noise level by up to 97 per cent compared to previous models. Any-layer HDI PCB technology and a 99.9 per cent pure copper shield ensure maximum signal purity and reduce electromagnetic interference. The elegant 6-inch display with 2K resolution and the 4.5th generation user interface combine functionality and design. The case made of polished 904L stainless steel and a PVD-coated ceramic back combines technological perfection with sophistication. A customised leather case made from the finest Perlinger calfskin rounds off the overall package. The SP4000 supports high-resolution PCM up to 32 bit/768 kHz as well as DSD512 and offers a wide range of applications with 3.5 mm and 4.4 mm headphone outputs and Bluetooth. With a playback time of up to 10 hours and 256 GB of internal memory, which can be expanded to up to 1.5 TB via microSD, the SP4000 is the ultimate choice for audiophile music lovers.
