Description

There has never been an introductory integrated amplifier with the 

fit, finish and sound of the 

Mystère

 ia11. There —we said it. At first 

glance, this amp simply takes your breath away; first, the proprietary 

finish, resembling something like deep, rich, black glass, although 

even those words don’t do it justice. Next, the fit: the way the tube 

cage secures so snugly with its quick-release banana plugs; the per-

fect alignment of the transformer covers; the fully-vented chassis; 

the heavy-gauge bottom plate…No expense spared.

Take a look inside—we encourage it. Point-to-point wired using 

premium parts; dual-layer, polypropylene coupling caps; low-noise 

resistors; high-purity copper conductors and the cleanest build 

quality you can find.

And sound? The ia11 produces 40 watts of the sweetest, purist 

sound you’ll ever hear. Specially-wound power and output trans-

formers deliver the kind of clean juice that makes the amp’s 40W 

sound like 80. The pentode push-pull design is built around 6SN7 

input/driver tubes and EL-34 power tubes that deliver a dynamic 

presentation. And you’ll never have to worry about biasing tubes; 

Mystère

 has incorporated a dual-mono Adaptive AutoBias circuit 

that automatically adjusts each tube to its sweet spot. Want to try 

different EL34s? Just plug them in! Topping it off, the ia11 utilizes a 

24-step volume attenuator, the kind of control found only on the 

most expensive, five-figure amps.
