{"product_id":"kora-tb-140-integrated-amplifier","title":"Kora TB 140 Integrated Amplifier","description":"\u003cp\u003eThe Kora TB 140 Integrated Amplifier embodies the essence of Kora’s acclaimed SquareTube® technology, blending the warmth of tubes with the drive and precision of transistors. Featuring 4 triodes per channel, the SquareTube® stage handles all amplification and signal control, delivering unmatched clarity, phase accuracy, and musical refinement. By using hyper-linear complementary transistors solely for current delivery, the TB 140 achieves a seamless synergy where tubes shape the sound and transistors unleash effortless energy. The result is a dynamic, natural, and highly stable amplifier that reveals hidden detail and musical nuance, even when driving complex speaker loads.\u003c\/p\u003e\n\u003ch5\u003eSquare Tube Technology\u003c\/h5\u003e\n\u003cp\u003eThe TB140 introduces listeners to Kora’s Square Tube Technology in its most approachable form, proving that high-end engineering can be both accessible and refined. All of the amplification and signal control happens in the tube stage; the transistors simply supply the current your speakers need without adding their own character, for grip and stability that keeps the music locked in place. This balance of warmth and precision makes the TB140 a standout entry point into Kora’s philosophy, offering a taste of their flagship design approach in a more compact and versatile package. \u003ca title=\"Learn more about Kora Square Tube Technology\" rel=\"noopener\" href=\"https:\/\/kora.fr\/en\/square-tube-2\/\" target=\"_blank\"\u003eLearn more about Square Tube Technology\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch5\u003eKey Features\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquareTube® Amplification\u003c\/strong\u003e: 4 triodes per channel for pure tube-driven signal control with transistor-backed current delivery.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase Accuracy\u003c\/strong\u003e: No phase shifts in low or high frequencies for precise, natural sound reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDynamic Energy\u003c\/strong\u003e: Tubes provide smoothness and warmth, while transistors deliver unlimited current and impact.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Stability\u003c\/strong\u003e: Maintains consistent performance with complex loads, ensuring reliability across demanding speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNatural Musicality\u003c\/strong\u003e: Extracts subtle details and dynamics from any source, offering lifelike soundstage and definition.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eThe Listening Room Difference\u003c\/h5\u003e\n\u003cp\u003eWe’re a third-generation family business with a brick-and-mortar showroom in Chestertown, Maryland, and a reputation built on trust, not hype.
