AUD $2,600 is optimistic for this unit. The i150 typically trades used in the AUD $1,800–$2,200 range depending on condition and age. This seller claims "barely 5 months old" and mint condition with full packaging, which supports asking higher than floor price, but AUD $2,600 sits above recent comparable sales. The official RRP sits around AUD $3,890, so you're looking at roughly 33% off retail—reasonable for a lightly used integrated, but not a steal. If the unit shows genuine minimal use and you value the room correction features and Class D amplification, it's defensible; otherwise, watch for similar listings below AUD $2,400.
Before committing, confirm the room correction software runs smoothly on your iOS device (it requires an Apple phone for calibration, which some buyers find limiting). Verify all original accessories are present—power cord, documentation, calibration files—since the i150's appeal hinges partly on its digital integration and preamp functionality. Ask how it was actually used those five months; if it sat mostly idle, check for any quirks powering up or with Bluetooth connectivity, as these are rare but worth ruling out.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
