Icon Audio MB90 MkII M Mono Block (Pair)

The new Tung Sol KT120 valve seems to have taken the Hi Fi world by storm! Taking the crown as the King of pentodes from GECs 1957 KT88. Icon Audio’s upgraded version of the KT120 power amplifier has several improvements including circuit and cosmetic improvements. Most importantly a built in bias meter greatly simplifies keeping your amplifier in peak performance. Previously you had to pay attention to numbers. Now if the pointer is on the black mark, it’s correct. Very easy!


The MB90 MK IIm is a very high performance power amplifier specifically designed to work in Triode and Ultralinear mode depending upon your preference and power needs. It can drive the very best of speakers with ease. Using only four valves the running cost and maintenance is very easy as the valves are run well within their maximum ratings

The front end is inspired by the famous British “Leak/Mullard” designs of the 1950s. This gives a very smooth musical quality to the high power available, making them very versatile in their application. Icon Audios unique big Tertiary wound “LDT” transformers give you true high end performance in every way: Dynamics. Macro Dynamics. Depth. Bandwidth. Purity. Warmth.
