Astell&Kern A&ultima SP2000

Deze A&ultima SP2000 is de nieuwe topspeler van Astell&Kern. De eerste Astell&Kern speler met een volledig gescheiden en onafhankelijk opgebouwd gebalanceerd circuit. De analoge hoofdtelefoonversterker is hierop geoptimaliseerd en er is meer vermogen beschikbaar (6Vrms gebalanceerd). De overige specificaties zijn grensverleggend. De dubbele Ak4499EQ DAC chips ondersteunen PCM in 32bit/768kHz en Native DSD22.4MHz. De Dual Band Wi-Fi (2.4/5GHz) is stabieler dan ooit door een verbeterde antenne. Met 512GB aan intern geheugen kan veel offline streaming content worden opgeslagen.
