Icon Audio Stereo 60 KT150 (MKIII) Integrated Amplifier


The new KT150 valves provide a further upgrade to the Stereo 60. Read the review by Hi Fi World.

ST60 KT150 Background story.

This is our biggest integrated amplifier. It is ideal for someone wanting a very dynamic fast sound. It has a big power supply, big output transformers, and the new Tung Sol KT120. And comes with many features.

The MK III design comes with our new “LDT” low distortion transformers, a valve regulated first stage, and a copper alloy top plate.

Integrated & Power Amplifier in One!

A special feature is the ability to change the sensitivity of Stereo 60 MKIII  at the flick of a switch. Choose between use as either a integrated remote control amplifier, or as a power amplifier fed from a separate pre-amplifier.

Triode and Ultralinear Amplifier in One

The triode sound is preferred by many hi fi fans, but the power is always lower. With our UL/Triode switch you can change from 65 watts to 35 watts of pure triode sound by changing the switch.
