Our best tube amplifier offering is the Icon Audio MB845 MKII Mono Blocks. Noel Keywood from HI FI World (UK) states " Amongst the best amplifiers I have ever heard".  For the discriminating Audiophile that wants the best. 

 

Custom configurated and ordered directly from the UK with an average delivery time of 3 - 4 weeks.

 

The “Reviewers Amplifier” With several pairs sold to leading reviewers, we are told that one of their outstanding qualities is the ability to give consistent results with virtually any type of speaker. Something many “high end” amplifiers cannot do. Like all our amplifiers the design is simple letting the magic of the valves shine through The RCA 845, probably the ultimate power triode valve dates from about 1931 when the only way to get higher powers was to make valves bigger and run at higher voltages. The later EL34 and KT88 types are far more efficient but many think do not sound as pleasing. When we first released the MB845 in the UK they were greeted with great acclaim by the hi fi press and customers, for power and value, but above all their unique sound quality. It has become THE reference valve amplifier for Hi Fi World magazine. Many other 845 amplifiers use 4 stages, often using 300B valves as driver valves, but this more complicated design does not allow the 845 to reach its full potential in terms of transparency and maximum output of 110w, useful if your speakers need a lot of power. But the power is secondary to the large bandwidth and low distortion available. For some people only a large triode valve like the 845 can give the golden warm tone which is so pleasing, with its feeling of air and space and sense of realism. The MB845 MK I has truly become a legend in the UK, but hi fi fans were soon asking if there was more we could do to improve the performance. With the MB845 MK II, we have used all our expertise to create our ultimate triode PP amplifier. The MB845 MK II has an improved power supply, an upgraded driver stage, more linear driver chokes, and our new series of bigger LDT series of low distortion transformers. These have caused the MB845s to put on 11kg each to 37Kg each, so be careful lifting! A feature of the MB845s is the high and low sensitivity. This enables MB845s to work with both “Passive” and conventional pre amplifiers. This is not done by attenuation which reduces quality, but genuinely changes the gain of the input. The sound is best described at “an iron fist in a velvet glove”. These amplifiers will suit almost any speaker and situation. They have no particular down side other than size and weight.
