New, the SMSL A300 was roughly US$196, so US$150 used is already a meaningful discount. Against nine recent used asks—US$140 at the 25th percentile, US$161 median, and US$196 at the 75th—this is a fair-to-good price, though not quite the bargain territory below US$140.
It is a capable little Class D integrated amplifier with useful real-world flexibility: about 85Wpc into 8 ohms, Bluetooth and USB alongside RCA, a remote, subwoofer pre-out, and a bridge mode for higher power. It makes a particularly tidy desktop or compact-room system and offers more functionality than a bare power amp. Since the listing gives no condition or accessory details, confirm that the remote, power supply, and inputs work; at US$150, a clean example with those included is a sensible buy.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
