A$2,700 is a bit ambitious versus the recent used market: it sits above the A$2,590 75th percentile, while the median comparable asking price is A$2,437. It is only about A$110 over the top quartile, so this is not wildly off; it just isn’t a bargain at current asking.
That said, this is a serious mono power amp, and March Audio gear is generally bought by people who want clean, high-current drive and a no-nonsense audiophile presentation. If the unit is genuinely tidy, original, and complete, the upside is getting a well-regarded amp without the usual new-gear depreciation. At this price, I’d want confirmation of condition, age, and any service history, but the listing is still credible for the right buyer.
