You’ve fallen in love with the dazzling appearance and captivating tube sound of Mystère’s ia11 but you want more; more power, more dynamics, more flexibility.
The ia21 is designed specifically for you. With larger, more powerful transformers, the ia21 delivers 50 watts per channel that sound like 100. Coupled with Mystère’s pentode, push-pull design, ia21’s sonics strike you immediately as smooth but lively, with rich tones, snappy transients and a stunning soundstage that puts you third row center.
The ia11 runs EL34 power tubes and comes with an Adaptive AutoBias circuit that automatically adjusts each tube to its sweet spot. The ia21 takes that process one step further.
The minds of Mystère have developed a special circuit that re-calibrates the Adaptive AutoBias board for EL34s or KT88s. One flick of a switch allows you to run either tube at its optimal level. You can play with power tubes forever, nudging the amp’s sound this way and that. Takes about a minute to swap 'em out!
The ia21 utilizes all the same high-quality point-to-point wiring, dual-layer, polypropylene coupling caps, low-noise resistors and high-purity copper conductors as found in the ia11. Top it off with an exceptionally-designed, 24-step volume attenuator and soft-start circuitry that prolongs the life of vacuum tubes and other critical components and you’ve got an integrated amp that will remain a centerpiece in any system for years to come.
