Kora TA 480 Class AB Stereo Amplifier

Kora TA 480 is a high-definition Class AB stereo power amplifier that pairs Kora’s proprietary SquareTube® operational amplifier with a powerful transistor output stage. Four triodes per channel deliver tube-like smoothness and rich detail, while complementary high-linearity power transistors supply the current required by demanding speakers. The hybrid design provides phase-accurate reproduction, limitless dynamics, and exceptional stability with complex loads — delivering both musical refinement and commanding power. This is the non-integrated version of the TB400.

Square Tube Technology

The TA480 showcases Kora’s innovative Square Tube Technology, a design that moves beyond traditional transistors to create a circuit that behaves like tubes without their limitations. In this integrated amplifier, Square Tube delivers lifelike dynamics, tonal warmth, and speed that bring music into sharper focus. The result is a listening experience with both intimacy and scale: the qualities that define the Kora sound.
