Topping Mini 300 Power Amplifier, Black Overview
The Topping Mini 300 Power Amplifier is a compact stereo amplifier for desktop hi-fi systems, home listening, and professional monitoring setups. Its fully balanced Class D design helps reduce interference and mains hum, giving you a clean signal with very low distortion. Delivering up to 140W per channel into 4 Ohms, it provides the power needed for a wide range of passive speakers while maintaining detailed, accurate playback.
You can connect balanced TRS or unbalanced RCA sources without extra adaptors, making it easy to integrate into an existing system. A built-in 12V trigger allows the amplifier to switch on and off alongside compatible equipment, helping simplify your setup. The all-aluminium chassis is compact enough for desktop use, while cooling vents on the sides and base improve heat dissipation during extended listening sessions. Silent power switching, along with built-in overheat and overcurrent protection, helps keep both the amplifier and connected speakers operating reliably.
