Against your own recent comparables, €2,500 lands above the 75th percentile of €2,511 only by a hair, so this is basically the top end of the market rather than a bargain. The median is €1,211 and the 25th percentile is €852, so the ask is clearly ambitious for a used interconnect in “good” condition.
That said, this is a well-regarded cable line with a strong following for its natural, low-fatigue presentation and good system synergy when the rest of the chain is already sorted. If the length, terminations, and plugs are exactly what you need, and the cable is original and tidy, there’s real appeal here; just don’t expect much room to negotiate unless the listing lacks proof of authenticity, complete packaging, or other key details.
