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.\u003c\/p\u003e\n\u003ch5\u003eSquare Tube Technology\u003c\/h5\u003e\n\u003cp\u003eThe TA480 showcases Kora’s innovative \u003ca rel=\"noopener\" href=\"https:\/\/kora.fr\/en\/square-tube-2\/\" target=\"_blank\"\u003eSquare Tube Technology\u003c\/a\u003e, a design that moves beyond traditional transistors to create a circuit that behaves like tubes without their limitations.
