This is an older budget Class D amp, so timing only matters insofar as you’re buying a proven, discontinued-style value piece rather than chasing a newer feature set. At US$55, it sits well below the US$70 25th percentile and far under the US$135 median, so this reads as a strong bargain rather than a merely fair ask.
What makes it worthwhile is simple: these SMSL amps have a reputation for compact, no-nonsense efficiency, enough power for small-to-medium speakers, and an easy setup with the original supply included. That accessory matters, and at this price the listing has real upside for a desktop, bedroom, or secondary system. Unless the unit has noise, channel imbalance, or a missing/weak power brick, this is the kind of used amp that’s easy to recommend.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
