The fair market price for a Nagaoka NM-11 A MM phono cartridge in AUD is estimated at AUD 450-650 for new or mint condition units, with used or good condition examples typically ranging from AUD 300-450, based on converted international listings and Australian replacement stylus pricing as proxies (no direct full-cartridge AUD listings found in recent data).
### Price Range Breakdown
- New/mint: AUD 450-650. This draws from a US used NM-11AS (similar model) at $359.95 USD (~AUD 540 at current exchange rates of ~1.50 USD/AUD), adjusted conservatively upward for new condition and import/shipping to Australia. Australian stylus replacements for NM-11 A (essential for full functionality) list at AUD 34.95, implying a complete new cartridge value well above entry-level Nagaoka models like the MP-110 at AUD 219.
- Used/good: AUD 300-450. Reflects discounts for wear (e.g., the listed stylus-sharp used US unit) and aligns with aftermarket stylus options at ~€29 (~AUD 48), suggesting rebuilds keep used values viable but lower.
### Key Factors Affecting Value
- Condition: New units command premiums due to original diamond stylus longevity; used prices drop 20-40% based on stylus wear and testing (e.g., "sharp and good working condition").
- Model variant: NM-11 A (spherical stylus) is entry-level; similar NM-11AS or upgrades affect pricing.
- Location/availability: Australian sites focus on styluses (AUD 35-50) rather than full cartridges, increasing import reliance and adding 10-20% for duties/shipping.
- Market trends: Limited direct listings indicate niche demand; values stable but could rise with vinyl resurgence (no user-reported sales in results).
Note: Estimates use conservative Feb 2026 exchange rates and prioritize AU-focused data; actual prices may vary by seller negotiations or stylus replacements.
