At US$500, this listing is a strong bargain for the SMSL M400, sitting well below its typical used market. The DAC retails new for roughly US$600–US$860 depending on the seller, with one source listing it at US$809 and another at US$601.99 after a sale. Since used prices for high-end desktop DACs like this usually hover near 70–80% of new, a US$500 ask lands near the 25th percentile of the used range—making it an excellent deal for a well-regarded unit.
The M400 is respected for its AKM AK4499EQ chipset, delivering 131dB dynamic range, fully balanced XLR outputs, and support for DSD512 and MQA. It also includes Bluetooth 5.0 with LDAC, HDMI, optical, and removable antenna dongle, making it versatile for both desktop and integrated setups. If the condition is clean and accessories are intact, this is a compelling buying opportunity for anyone seeking top-tier AKM performance without paying full retail.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
