The Corton-Charlemagne 80 has a strong reputation as a refined, high-touch Shindo monoblock, but at €34,000 this asking price is well above the typical used level for this model. Recent used references I can verify put a pair around roughly €11,000 to €13,000 in the market, so €34,000 is an ambitious ask unless this is an unusually complete, mint, or provenance-rich package.
What makes it appealing is the usual Shindo mix of tone density, texture, and ease with real-world speakers; owners tend to prize these amps for musical flow more than brute-force specs. If the pair is clean, original, properly serviced, and comes with documentation or rare accessories, that supports the premium, but you’d still want strong proof of condition and service history at this level.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
