US$1,000 is fair here: it lands exactly on the median of the recent comparable USD listings, with both the 25th and 75th percentile also at US$1,000. That means there’s no real pricing premium to push back on, but also no obvious bargain markup advantage; at this number, the value is basically in the amp itself, not in an under-market ask.
The GSX Mini is well regarded for its clean, highly resolving solid-state drive and excellent control with demanding headphones, so a tidy example can be a very sensible buy at US$1,000. For a listing like this, the main upside is getting a respected reference-grade amp without paying a scarcity premium; if the unit is clean, quiet, and includes the original packaging or power supply, it reads as a solid enthusiast purchase.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
