The Kora TB400 is a stereo integrated amplifier from Kora, a French manufacturer specialising in valve amplification. It is part of Kora's integrated amplifier range.
Key specs that matter
The TB400 is rated at 2 x 200 W into 8 ohms and 2 x 360 W into 4 ohms. It has four single-ended analogue inputs with an input sensitivity of 1,000 mV and an input impedance of 15 kOhm. Frequency response is 20 Hz to 20 kHz. The chassis measures 130 x 420 x 420 mm and the amplifier weighs 27 kg.
Pairing
With four line inputs, the TB400 can serve a modest to moderate set of sources without an external switcher, and its output into 4 ohms leaves room for lower-impedance loudspeakers.
Alternatives
The Kora TB200 is a smaller integrated amplifier in the same range.
