For those seeking an even higher level of audio quality, AURALiC offers an optional upgrade: the S1 External Purer-Power Supply Unit. This unit bypasses the internal power supply of the ARIES S1 and VEGA S1, doubling the power capacity for enhanced performance. Featuring two dedicated transformers and Purer-Power low noise power supply circuits, the upgraded unit ensures a total galvanic isolation between the Tesla G3 processing circuit and audio circuits. This separation eliminates interference and minimises noise, resulting in superior sonic performance that elevates your listening experience to new heights.
