At €11,200, this looks well below the usual used market for a Piano G2 and reads as a strong buy if the speakers are genuinely clean and fully functional. Comparable TIDAL Piano G2 listings I found sit around €12,500, €14,500, and up into the €25,000–€31,000 range depending on finish and variant, with even a used TIDAL-approved pair at €32,000 and a new listing at €45,000.
That makes this asking price attractive for a speaker known for very high resolution, refined treble, and serious cabinet/fit-and-finish; the Piano G2 was TIDAL’s entry model, but still squarely in ultra-high-end territory. If the condition is truly good, the main upside is simply getting into a rare, prestige-level loudspeaker at a price that leaves room for shipping, setup, or future service; I’d just confirm the exact finish, whether it’s a matched pair, and that stands, grilles, and packing are included.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
