At US$12,500, this is well above the recent used market for this processor, which clusters around a US$2,100 median with a US$1,769–US$4,601 typical band; by that yardstick, the asking price is ambitious and only makes sense if the seller can prove unusually strong provenance or extras. Even allowing for Lyngdorf’s reputation, this needs to be justified against the current-generation new price and a very clear feature delta.
That said, the MP-60 is a serious reference-grade processor: Lyngdorf is respected for room correction, clean digital architecture, and flexible integration in high-end theater setups, and the AES67 upgrade can be meaningful for networked audio users. If this is truly demo-only with low hours, original packaging, and a full accessory set, it’s a polished piece worth chasing—but at this number, I’d want documentation, firmware status, and the exact upgrade history before calling it compelling.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
