This is more a buyer’s market than a seller’s market for the Manger C1 at A$11,600, because that lands above a typical used reference point of roughly A$12,700–A$17,400 equivalent for known listings and current retail, but still below new pricing in the same orbit. That makes the ask fair-to-strong, not a steal; if you’re comparing against the lower used examples, it’s on the firm side, but not out of line for a clean very_good pair.
What makes it worth considering is the C1’s reputation for speed, coherence, and precise imaging from Manger’s wideband driver concept, which is the real draw for listeners who value timing and midrange realism. A well-kept pair can be a genuinely special long-term monitor buy, especially if it’s complete with original packaging, stands, or documentation. At this price, I’d mainly want confirmation of full working order, matching serials, and no history of amp or driver issues, but a tidy listing like this still reads as an attractive audition if the condition is genuinely as described.
