{"title":"Kora Integrated Amplifiers","description":"\u003cp\u003eKora's integrated amplifiers bring the full force of their patented SquareTube technology into single-chassis designs that combine preamplification and power amplification without compromise. Designed and built in Toulouse, France, by engineers with aerospace backgrounds in power supply and signal treatment, each integrated uses four triodes per channel in a symmetrical configuration. This is not hybrid amplification in the conventional sense. The SquareTube circuit functions as a true tube amplifier, with transistors assisting the output stage rather than replacing it.\u003c\/p\u003e\u003cp\u003eThe lineup scales from the \u003ca href=\"\/products\/kora-tb-140-integrated-amplifier\"\u003eTB 140\u003c\/a\u003e at 70 watts per channel through the \u003ca href=\"\/products\/kora-tb-200-integrated-amplifier\"\u003eTB 200\u003c\/a\u003e at 100 watts, up to the \u003ca href=\"\/products\/kora-tb-400-integrated-amplifier\"\u003eTB 400\u003c\/a\u003e delivering 200 watts of Class AB power.

More filtering, bigger transformers, more transistors.\u003c\/p\u003e\n\u003cp\u003eAt its heart lies the innovative SquareTube® operational amplifier, equipped with four triodes per channel. This unique design ensures that all amplification and signal control functions are handled by the SquareTube®, while complementary hyper-linear power transistors supply the necessary current to drive your speakers without coloring the signal. The result is an amplifier that maintains absolute phase accuracy, delivers extraordinary detail, and achieves natural dynamics with unmatched musicality.\u003c\/p\u003e\n\u003cp\u003eBy eliminating the limitations of traditional output transformers, the TB400 avoids phase shifts, poor coupling, and current restrictions. Its marriage of high-voltage tube smoothness and transistor-driven energy delivers a rich, stable, and precise performance—even under complex load conditions.
