A product for purists

Starke Sound’s multi-channel amplifiers have long set the standard in home theater and high-fidelity audio.The A Series is engineered with a single mission: combine immense power with flawless sound fidelity to redefine what a multi-channel amplifier can achieve.

The A3, a 3-channel amplifier, features our third-generation Class A+AB design, delivering up to 620 watts per channel at 4Ω with a fully balanced topology and a robust power supply capacitor array of up to 176,000 µF.Its ultra-high bias design ensures pure Class A operation for nearly all music and audio signals, while seamlessly transitioning to Class AB for extremely large signals—typically less than 1% of content—preserving the system’s full dynamic range.The result is a pure Class A experience with exceptional power reserves.

A hybrid heat dissipation system, combining aluminum alloy and copper, eliminates the need for fans, providing silent operation without compromising performance.For added versatility, the center channel features an input switch that, when deactivated, transforms the A3 into a 2-channel amplifier with increased power supply reserves for even greater performance.Ultra-low distortion, abundant energy reserves, and fan-free operation make the A3 an ideal centerpiece for high-end home theater and Hi-Fi systems, satisfying the demands of the most discerning audiophiles.
