Compared with a new cable in this category, A$3,600 is firmly in used high-end territory, but it is ambitious versus the recent AUD comps: the median is A$2,112 and the 75th percentile is A$2,763, so this asks a clear premium over the usual market. It is above the top quartile, so I’d only call it good value if it includes uncommon extras or there’s a strong reason to pay for this exact specimen.
What makes it worth a look is that Synergistic Research’s Atmosphere digital cables are well-regarded for bringing a more open, low-noise, highly resolved presentation, especially in systems that already reveal cable changes. In excellent condition, this is the kind of piece that can be a meaningful upgrade buy if you specifically want that house sound and the length/spec matches your setup; otherwise, the price leaves less room for experimentation than the median listing.
