At £14,587, this sits above the recent used median of £10,828 and also above the £12,243 75th percentile, so it reads as ambitious rather than fair-market priced. It’s not wildly off, but you are paying a clear premium versus the typical used pool, so I’d want evidence of standout condition, provenance, or extras to justify it.
That premium can still make sense on a SW1X monoblock if the pair is clean, properly matched, and comes from a careful system; these are the sort of amps buyers chase for grip, scale, and refinement, and good examples can hold value well. At this level, the main things to confirm are cosmetic condition, service history, and whether any original packaging, manuals, or accessories are included, because those details matter more when the price is already at the top end.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
