This is a buyer’s market for the DA-9 class: a discontinued desktop amp with strong measurements, and A$250 lands right around its original launch price, so it’s only a fair-to-good used ask, not a bargain. In used terms, I’d want to see it closer to A$180–A$220 to call it especially attractive; at A$250 it’s still reasonable if the condition is genuinely clean and it includes the power supply and antenna.
What makes it worth a look is the combination of balanced XLR/RCA inputs, Bluetooth 5.0 with aptX, and very solid output for a small chassis: up to 90 W per channel into 4 Ω and 50 W into 8 Ω. It’s a tidy, high-value desktop amp for efficient bookshelves or a nearfield setup, and the low-noise, high-separation design has earned it a good reputation among compact Class D amps. If the listing is original-owner and complete, that adds real appeal here.
