Icon AudioStereo 60 MkIII

Size, style, sumptuous sound: Icon Audio's handmade ST60 MKIIIm has it all, along with the boast of being the world's first KT150 integrated ultralinear/triode hi-fi tube amplifier. That's right: A simple flick of a switch takes this UK-designed unit from 80 watts in ultralinear mode to 40 watts of pure triode. Tailor-made for listeners that want a bigger, more robust integrated--and designed to present graceful music in hyper-detailed fashion and rocking fare sans harshness, tizz, or glare--it touts a big power supply, big output transformers, and dynamic, fast sound.

As Icon's biggest integrated amplifier, the ST60 MKIIIm also serves as power amplifier. The ability to change its sensitivity via basic switch means you can opt between the component serving as an integrated remote-control amp or power amp fed via a separate preamplifier. Three potted transformers reduce transfer noise, and the presence of the KT150--with 50% more power than the KT88--immediately yields improvements in sonics, power, and balances.

Like all Icon amps, the ST60 MKIIIm is entirely point-to-point hand-wired and contains no printed circuit boards or transistors, which degrade valve performance and color the signals. A cool built-in meter both adds to the classy, vintage look and serves multiple purposes, telling you when the output valves needs replacing as well as if they're operating at maximum potential. It's all in the service of ensuring that you're hearing music in the finest-possible sound. Along the same lines, the tertiary transformers reduce distortion and global feedback.
