Description
Description
The Kora TB 200 Integrated Amplifier embodies the essence of the Kora amplifier range, powered by the revolutionary Square Tube® operational amplifier. With four triodes per channel, this unique design delivers remarkable musical qualities, seamlessly blending tube smoothness with transistor-driven power. Unlike traditional output transformers, the Square Tube® and transistor combination ensures absolute phase accuracy, extended frequency response, and limitless current delivery. The result is an amplifier that reveals stunning detail, natural dynamics, and effortless energy, even when driving complex loudspeakers.
Square Tube Technology
In the TB200, Kora applies its patented Square Tube Technology to deliver musical truth with both finesse and authority. The design begins with tube stages that set the tonal character, adding natural texture and harmonic depth, then passes to a solid-state section that ensures control, dynamics, and long-term stability. This combination makes the TB200 equally capable of handling delicate passages and explosive peaks, creating a listening experience that feels both intimate and powerful.
