The AURALiC ARIES S1 is a respected, all-in-one streaming processor known for its robust DAC and flexible file support, but the A$2,800 asking price here is ambitious compared to the typical used market. Based on your database of five recent AUD listings, the median sits at A$1,663, with the 75th percentile at A$2,469; this listing exceeds that upper bound by A$331, placing it well above fair value for a used unit even in like-new condition.
That premium buys you a highly regarded streamer that handles everything from lossless AIFF to MQA with ease, and its integrated design avoids the need for external power unless you opt for the upgraded supply. If the seller includes original packaging, warranty transfer, or the optional Purer-Power supply, the gap narrows slightly, but without those extras, A$2,800 is tough to justify against the A$1,564–A$2,469 band where most comparable units land.
