At US$129, this sits well below the usual new price for the AO200 family, which has been around US$249–US$280 depending on version and review source. For a functioning original AO200, that makes the asking price look like a strong buy rather than a stretch, especially if the unit is complete and cosmetically clean.
What makes it worth chasing is the appeal of SMSL’s compact Class D formula: lots of power for the size, low distortion, and a straightforward integrated-amp setup that has earned a good reputation for clean, controlled sound. If it includes the remote and power supply and there’s no sign of thermal or connector abuse, this is the kind of small-form-factor amp that can be an easy win for a desktop or secondary system.
