This Astell & Kern A&ultima SP3000M (to give it its full name) is a modern day all feature connected portable audio player. It is based on, and is the successor to, Astell & Kern’s flagship SP3000 portable device. The SP3000M music player has four AK4499EX DACs and two separate AK4191EQ chips that handle digital signals. A Snapdragon 6125 Octa-core processor manages the system interface, making the user experience “stable with fast and fluid movement.” The SP3000M uses an internal shield to prevent noise and electromagnetic interference from affecting the audio block.
