APL DSD-SR SE Digital Analog Converter

Der DSD-SR SE ist der aktuelle Referenz-Digital/Analog-Wandler von APL in Halbleitertechnik.

Der DSD-SR SE wurde speziell für begeisterte Audiophile entwickelt, die auf der Suche nach der natürlichsten und analogsten digitalen Audiowiedergabe sind, die ein reines Solid-State-DAC-Design zu bieten hat.

Er ist ein handgefertigtes Boutique-Gerät, das mit Blick auf die bestmögliche Audioqualität in seiner Preisklasse entwickelt und gebaut wurde.

Der DSD-SR SE ist von der Klangqualität des Vinyls inspiriert und bietet einen vergleichbar natürlichen, reichen und räumlichen Klangcharakter.

Von der vierfachen DSD-Verarbeitungsrate bis hin zur transformatorgekoppelten Class-A-Ausgangsstufe bietet der DSD-SR SE ein hohes Maß an technischem Fortschritt und Raffinesse.

Der DSD-SR SE ist die letzte Special Edition für dieses Modell.
