At US$150, this used SMSL DA-9 is a clear bargain, sitting well below the typical used market range of US$180–US$220 for this discontinued model, which originally retailed around US$250. Since the asking price is near the 25th percentile of recent used listings, it represents a strong deal for a buyer seeking high performance at a minimal cost.
The DA-9 is well-regarded for its fully balanced circuit, 90W into 4Ω output, and Bluetooth 5.0 with aptX, making it a versatile desktop or small-room amplifier. Its Infineon class D chips deliver 92% efficiency with minimal distortion, and the inclusion of a remote, subwoofer out, and 8 EQ modes adds meaningful upside. As a discontinued unit, finding one in unknown condition at this price is a timely buying opportunity, especially for enthusiasts who value its compact CNC design and patented SMSL SDB sound.
