This is a seller’s market for this category at this asking price: US$27,500 is far above the comparable-market median of US$2,100 and even well beyond the 75th percentile of US$4,520, so it reads as very ambitious rather than fair value. For a buyer, that means the price only makes sense if this is a genuinely exceptional, complete system with documented condition, premium installation value, and strong accessory/package inclusions.
The upside here is that Steinway Lyngdorf systems are respected for their room-correction, clean amplification, and high-end home-theater integration, so a well-kept example can be a serious one-and-done solution. At this level, I’d want proof of original components, calibration hardware, firmware status, and any custom install parts; if it’s fully intact and turnkey, it could justify a premium, but without that, the listing is priced for a very selective buyer.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
