The TB140 is an integrated amplifier from Kora, a French manufacturer known for considered electronics engineering, built with a dedicated phono input alongside four line-level inputs. The TB140 brings Kora's considered engineering to a complete integrated solution.
Key specs that matter
Four single-ended inputs plus a dedicated phono input are provided, with input impedance at 15k ohms and output impedance at 2,000 ohms. MM/MC phono current-sensing input impedance is the standard 47k ohms. Output power is 2 x 70W into 8 ohms, rising to 2 x 140W into 4 ohms - a textbook power doubling indicating a robust, well-regulated power supply. Frequency response spans 20Hz to 20,000Hz within plus-or-minus 3dB. At 118 x 420 x 370mm and 9.5kg, the TB140 maintains a manageable integrated amplifier footprint.
Sound and use context
Expect the considered, dependable character Kora's broader French electronics catalogue is known for, with the built-in phono input covering vinyl playback directly without needing a separate outboard phono stage.
Pairing
The built-in phono input covers a turntable directly, and the clean power doubling into 4 ohms suits a wide range of loudspeaker impedances.
Alternatives
Kora's own TB200 sits above this model with considerably greater output, worth comparing directly to find the right Kora integrated amplifier tier.
