17 market transactions via web search — not HiFi Registry sales.

Understanding the market

Half of recorded transactions fall between $99 and $235. The full observed range is unusually wide — the highest recorded price is 11.0× the lowest. A spread that wide usually means the recorded sales are not strictly comparable: different configurations or finishes, units sold for parts or with cosmetic damage, or listings where the model name is shared across more than one variant. Treat the middle range as the useful signal and the extremes as outliers worth investigating before you price against them.

What buyers should know

Confirm the terminations are intact and have not been re-soldered, and check the length matches your needs, since cables are difficult to resell in unusual lengths. Counterfeit cable from well-known brands is a real risk — buy from sellers who can establish provenance.

This range reflects 17 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. That is a large enough sample to price against with reasonable confidence, though condition and provenance still move individual units.
