Icon Audio MB90 MK IIm Pentode Monoblocks
Front End Inspired by the Legendary Leak/Mullard Designs of the 1950s
Newly Updated: More Pure Class A Power, Increased Output, Augmented Power Supply, Boosted Bandwith, Front-Panel Bias Meter
Meet the New King of the Pentodes: Looks as Amazing as it Sounds
Cherished British tradition lives on. Icon Audio's MB90 MKIIm pentode monoblock power amplifiers are proudly inspired by the legendary English Leak/Mullard designs of the 1950s. The influence may be retro, but the sound of these KT120-based units is timeless: Smooth, warm, and free of fatigue. It all means you can listen to music longer, listen to more music, and hear more from your favorite music.
Plus, the updated MB90 is even better than its vaunted predecessors, with more Class A power, output increased from 100 to 115 watts, an augmented power supply, and boosted bandwidth. It's no wonder Icon has dubbed it the King of Pentodes.
Microdynamics, macrodynamics, and everything in between positively sing courtesy of the MB90 MKIIm's massive power and bandwidth. Ideal for listeners looking to replace a larger transistor amp or those that prefer a fast-sounding amp that possesses uncommon warmth, it outputs 110 watts in ultralinear mode or 60 watts in triode. Talk about getting the best of both worlds.
From aesthetic and manufacturing perspectives, Icon's signature monoblock is equally impressive. Like all Icon amps, the MB90 MKIIm is entirely point-to-point hand-wired. A cool, front-panel bias meter both adds to the classy, vintage look and serves multiple purposes, telling you when your amp is achieving peak performance. It's all in the service of ensuring that you're hearing music in the finest-possible sound. Striving to attain the same goal, the tertiary winding output transformers reduce distortion and global feedback.
An all-Triode Class A front end, larger choke-regulated power supply, plexiglas valve cover, silver-plated pure copper PTFE audio cable, gold-plated input and speaker terminals, and copper alloy top plate are also standard. Icon takes any worry out of the purchase by providing a two-year parts-and-labor warranty and full service and support for the lifetime of the product. That's how it should be, and while most competitors don't go to such extremes, Icon is happy to do so.
