Kora's power amplifier range spans Class A and Class AB topologies, all built around their patented SquareTube operational amplifier. Developed by aerospace engineers in Toulouse, France, the SquareTube circuit uses four triodes per channel in a symmetrical arrangement, creating a proper tube amplification stage that delivers voltage directly to the output. The transistor section handles current delivery, not signal amplification. The result is tube-grade musicality with the grip and control of solid-state power reserves.
The Class A lineup includes the CSA 270 stereo amplifier and the CSA 1150 and CSA 1200 monoblocks, alongside the CSA 2120 stereo. For Class AB efficiency with SquareTube character, the TA 240 and TA 480 deliver 120 and 240 watts per channel respectively. Pair with Kora's preamplifiers for a full separates system.
