Overview

The Stereo MKI was Icon Audio's first model in 2001 and has always remained a special product. Since that time, it has improved significantly over the years.
In its latest guise, the MKIII has received several upgrades:

-- Headphone jack.
Following customer feedback, the new model now has this feature. More flexibility in use.

--Improved nutrition.
Combined with our redesigned output transformers, the amplifier in ultra-linear mode now delivers over 50 watts.
The power in the triode mode has also increased to 30 watts.

--Redesigned control circuit.
Using a "cascade" configuration in the first stage, we can use a 6SN7 for all control circuit functions. This gives better definition while improving the frequency response at lower volumes.

--Choke regulated power supply
Together with the smoothing capacitors, the large choke gives super-smooth power control for a quiet background.
Tertiary transformers have an extra (third) winding that reduces distortion, with less global feedback. We believe that our large handmade output transformers are among the best. They are more expensive and harder to make, but worth it.

--Low feedback
Too much feedback can spoil the sound of an amplifier. We only use a small amount in the Stereo 40 MKIII.

Ultralinear or Triode?
For sixty years, hi-fi fans have debated which sound is better. With the Stereo 40 IV you can choose from both at the push of a button. Most hi-fi fans prefer the sound in triode mode.

--Remote control
Handy for getting just the right volume in your listening seat position. This allows the correct sound level to be accurately adjusted.
