Professional-Grade Audio Performance in a Compact Size

The Mini 300 delivers professional-grade audio performance despite its compact size. With ultra-low distortion levels and a fully balanced design, it produces clear, precise, and dynamic audio. It is the ideal amplifier for audiophiles and professionals who need a powerful yet portable solution for high-fidelity sound.

Fully Balanced Architecture for Purity and Clarity

Mini 300’s fully balanced architecture enhances noise immunity and minimizes interference, delivering a clean and transparent audio experience. By effectively eliminating mains hum, this design ensures exceptional audio quality, maintaining a pure background that faithfully reproduces every detail.

High Power Output with Ultra-Low Distortion

The Mini 300 delivers up to 140W x 2 into 4Ω, combining high power output with ultra-low distortion for a professional-grade audio experience. With a 5W output at a 4Ω load, the THD+N is as low as <0.0005%, and at 8Ω, it reaches <0.0004%. Whether you are listening to subtle vocals or large-scale orchestral works, the Mini 300 handles it all with ease, ensuring a dynamic range that stays true to the original recording.

Compact Design with All-Aluminum Chassis

The Mini 300 comes in a sleek, all-aluminum chassis, available in three finishes. This design not only enhances the amplifier’s durability but also improves heat dissipation, ensuring optimal performance even under heavy use. The stylish exterior is matched with the efficient internal architecture that guarantees minimal interference.

TRIG Linked Power Control for Seamless Operation

Equipped with TRIG linked power control, the Mini 300 automatically powers on or off in sync with other connected devices, eliminating the hassle of managing multiple units. This feature enhances convenience and ensures smooth integration into your audio setup.

Zero-Noise Operation and Built-In Protection

Mini 300 ensures a noise-free operation with its ultra-low noise floor (<15 μVrms). Additionally, built-in overheat and overcurrent protection safeguard your components, preventing any accidental damage and ensuring reliable performance during long listening sessions.
