An optimised power supply, a directly mains-powered power amplifier section and other key design features ensure high performance and reliability.

The 140 W (RMS) per channel (into 8 ohms) K3 Power Amplifier offers a simple yet very effective route for upgrading the musical performance of your system.

With a smooth and solid sound, the K3 Power Amplifier can be used in combination with the K3 Integrated Amplifier to form a bi-amplified or even tri-amplified system (with compatible speaker systems) delivering the ultimate power and control to your loudspeakers. Offering balanced XLR and single-ended RCA inputs and outputs, the K3 Power Amplifier will fit in with nearly all audio systems.
