TOPPING Mini300 – a Tiny Amplifier with 140 Watts of Power

05.12.2025 06:57 | ~1 minute read

 TOPPING has introduced the TOPPING Mini300 integrated amplifier, delivering 2 x 140 watts of power into an 8 ohm load. Housed in a miniature enclosure, the model utilizes fully balanced Class D amplification with a THD of less than 0.0004%. Trigger control allows for easy integration into existing audio systems.

The signal-to-noise ratio of 124 dB and the equally high dynamic range are impressive figures, quite unusual for this price range. Two inputs are provided for connecting sources: balanced and single-ended.

Despite its high output power, the TOPPING Mini300 amplifier remains compact. Its aluminum construction not only provides rigidity and protection from external interference but also improves heat dissipation, further aided by ventilation slots on the sides and bottom. The amplifier is available in three color options: Silver, Black, and White.
