Are you looking for a compact all-in-one system rather than separates? At USD 100, this is a strong bargain: it sits well below the comparable-listing 25th percentile of USD 185, with a median of USD 192 and 75th percentile of USD 213. Even allowing for the unknown condition, the price leaves substantial room for a very good buy.
The AO300 is a capable little powerhouse, combining a clean, punchy Class D speaker amplifier with DAC, Bluetooth, USB, optical, coaxial, HDMI ARC, subwoofer output, and headphone connections. Its broad connectivity and neutral, detailed presentation make it especially useful for desktop, compact-room, or minimalist systems, while its speaker output is generally the stronger feature. Before paying, confirm that it powers up, the display and remote work, both channels function, and the accessories—particularly the remote and Bluetooth antenna—are present. At USD 100, a successful basic test would make this worth pursuing.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
