Roksan K3 Power Amplifier


The K3 Power Amplifier offers an excellent value option for upgrading any audio separates component system, with clarity, detail and power in abundance. In addition to being compatible with most audio systems, it is also the natural partner for the K3 Integrated Amplifier and is the perfect way to upgrade your K3 system to offer more headroom, grip and control.

It can be used as a straight forward pre-power combination with the K3 Integrated or to form a bi-amplification (or tri-amplification) system for the ultimate drive and power to your loudspeakers. Whichever way it is used, the smooth and powerful sound of the K3 Power Amplifier will be a superb synergic improvement to your system.

   Frequently Asked Questions and Answers

  • What is the difference between an Integrated Amplifier, Pre-Amplifier & Power Amplifier?

    An amplifier has 2 main internal sections. The switching & control section is called the Pre-Amplifier, this allows you to select your source & volume & sometimes allows tonal adjustment. The Power Amplifier then takes the signal from the Pre-Amplifier & amplifies it to power your speakers. An Integrated amplifier has both the Pre-Amplifier & Power Amplifier combined into a single box.

  • Can I upgrade my Amplifier with a Power Amplifier?

    Some Integrated amplifiers have a pair of 'Pre-Out' sockets on the back which can be connected to an external Power Amplifier to upgrade your system. Please check the rear of your amplifier or Contact us with your model number for personalised advice.
