OUR RANGE
POWER AMPLIFIERS :
CLASS A
Kora CSA 270 : 2 x 70 W
Small stereo amplifier for pure Class A amplification. The combination of the Square Tube with pure Class A and a highly filtered linear power supply provides powerful amplification, but always within its comfort zone. The signal is delivered and revealed to the speakers as it is. If you wish, you can set the units to automatic mode.
ON/OFF management: lights up if a signal is present at the input, otherwise goes out.
Current management: switches to high or low current depending on the needs of the loudspeaker, to avoid unnecessary consumption.

INTEGRATED AMPLIFIERS :
CLASS AB
Kora TB140 : 2 x 70 W
Small and efficient, but uncompromisingly built, this integrated amplifier is our first model. All the amplification is done by tubes. But it’s still in its comfort zone : no saturation, no distortion. This is possible because the output power is distributed by 4 complementary highly linear power transistors. It’s also possible to adjust the balance between left and right, as well as the offset on each input.
General characteristics :
DIMENSION : 118 x 420 x 370 mm
WEIGHT : 9,5 kg
MATERIALS : Aluminium and steel
FINISH : Mineral grey
ACCESSORIES : Power cord, remote, instructions
POWER SUPPLY TRANSFORMER : 1 x 300 VA
MAIN FILTERING : 2 x 44 000 µF

INPUTS-OUTPUTS : Phono MM, 4 line inputs, Pre-out
Kora TB200 : 2 x 100 W
Even with all the amplification provided by the tubes, this integrated amplifier remains in its comfort zone: no saturation, no distortion. This is possible because the output power is distributed by 12 complementary highly linear power transistors. It is also possible to adjust the balance between left and right, as well as the offset on each input. An input can be configured as a “bypass” input or even as a pre-amplification output.

Kora TB400 : 2 x 200 W
The TB400 is, quite simply, the TB200’s big brother. More filtering, bigger transformers, more transistors. Output power is now distributed by 20 complementary highly linear power transistors. It is also possible to adjust the balance between left and right, as well as the offset on each input. An input can be configured as a “bypass” input or even as a pre-amplification output.

SERIES 140 :
Kora PR140
The reproduction of the tiniest details and respected dynamics give the PR140 preamplifier a smooth, precise musicality and a natural feel. In addition to the basic functions (volume, balance), the PR140 lets you balance the level of each of the five inputs. Your PR140 can be extended! This is an option that can be added to your preamplifier. It comes in the form of a drawer that you can place yourself to extend the range of possibilities of your device. A phono option: so you can plug in your vinyl turntable. A DAC option: for connecting your digital signals.

Kora CD140
After collecting the signal from the CD, AKM’s up sampler upsamples the signal to 768 kHz. This allows the signal to be filtered at higher frequencies, removing the residue of digital conversion from the audible band. All the clocks in the digital part are synchronised with the original signal from the CD. A ROHM DAC takes care of the 32-bit 768 kHz conversion. The Square Tube® ensures smooth, precise musicality. Supplied with high voltage, the output stage has no amplitude limits: the signal dynamics remain natural. With an output filter made of pure analogue, the respect of phases provides exceptional spatialisation. A three dimensional soundstage !
