There has never been an introductory integrated amplifier with the fit, finish and sound of the Mystère ia11. There‚ we've said it.

At first glance, this amp simply takes your breath away. The proprietary finish? Like deep, rich, black glass. And the fit? Perfect. Everywhere. The snugly secured tube cage. The precisely aligned 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? Specially-wound power and output transformers 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 the ia11's dual-mono Adaptive AutoBias circuit 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. It's the type of control found only on the most expensive, five-figure amps‚ perfect for the incredibly rich sound produced by this amazing introductory integrated amp.

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 stunningly lifelike soundstage.

Flexibility comes with an advancement to Mystère's proprietary Adaptive AutoBias board. Our engineers have developed a special circuit that re-calibrates the board for EL34s or KT88s. One flick of a switch allows you to run either tube at its optimal level. It's now fifth-grader easy to experiment with power tubes, gently nudging the amp's sound in different directions.

The ia21 utilizes the same high-quality point-to-point wiring, dual-layer, polypropylene caps, low-noise resistors and high-purity copper conductors as its little brother.

Top it off with our 24-step volume attenuator and soft-start circuitry that prolongs the life of the tubes and other critical components and you've got an integrated amp that will remain a centerpiece in any system for years to come.

The designs of Mystère separates represent so much more than simply 'splitting' the integrateds into pre and power stages technique common in the industry today. Like all our separates, its chassis provides space, a tremendous advantage. More space means less restrictive designs for improved power supplies and for the most advantageous wiring positions.

The ca11 uses an SRPP (Series Regulated Push-Pull) circuit for high gain, low distortion and very low output impedance by using a variation of the White Cathode Follower. The circuit uses no negative feedback for more natural tonality.

We continue to use our high quality, heavy duty, 24-step volume attenuator and fast, wide-band polypropylene caps. Like all our products, the pre amps are point-to-point hand-wired with rigid copper wire, loosely insulated with woven, silk tubing.

Implement the ca11 with either the pa11 or pa21 into your current system and you'll hear an immediate and profound improvement‚ a huge step on the road to perfection.

Synergy. The whole greater than the sum of its parts. You know it as one plus one equals three. But you've never really heard it. Until now. Introducing the ca21, our flagship preamplifier. It's larger chassis is designed to match aesthetically with the pa21 stereo power amp. And sonically, the combination off the two is otherworldly.

The ca21's full-size chassis provides a much larger playground for Mystère's European engineers. It gives them space, a tremendous advantage for less restrictive designs, for more and improved power supplies, and for the most advantageous wiring positions.

It takes a lot of trial and error to find the best route for wires; the more space, the more options, but ultimately, the better the result. With these separates, the results are phenomenal.

Like the ca11, the ca21 uses an SRPP (Series Regulated Push-Pull) circuit for high gain, low distortion and very low output impedance by using a variation of the White Cathode Follower. The circuit uses no negative feedback for more natural tonality.

It uses a single 5AR4 for rectification followed by a massive pi network consisting of a big inductor, separate left and right channel capacitors, regulator circuits and DC filament supplies.

Further improvements are realized by using a larger power transformer and increased power supply filtration. Add this together with high quality, heavy duty, 24-step volume attenuator and fast, wide-band polypropylene caps, point-to-point wiring with rigid copper wire, loosely insulated with silk tubing and you have a linestage preamp second to none.

The Mystère pa11 is the natural evolution of the critically acclaimed ia11 integrated amplifier. You get the same 40 watts of pure pentode operation and the rich, piano-gloss black finish but with a separate chassis for just the power stage, you can bet we've added a host of upgrades.

When we break down our integrated amplifiers into separates, we offer much more than the pre- or power stage of that integrated. So while the pa11 power amp evolves from the critically-acclaimed ia11, it offers much more. For instance...

We once again offer 40 watts of pure pentode output per channel, maintaining all the glory and beauty of tubes. However, the transformers in the pa11 are completely different, providing much more efficient power that delivers incredible depth and punch. We do implement a very modest amount of global negative feedback to make the amp rock solid.

We also use a high power, low impedance, solid state rectification circuit followed by a massive pi network using the highest quality caps and resistors. In the signal path are only two high quality Solen coupling capacitors.

Finally, we implement Mystère's proprietary Adaptive AutoBias circuit, specifically tuned for Pentode operation. Optimized for EL34s (but allowing for many others) the AutoBias circuit is continuously tweaking each tube to its sweet spot. No biasing, no need for matched tubes, no worries.

Combine the pa11 with the ca11 preamplfier, and you will enjoy the finest quality parts and design, with sound rivaling systems costing twice as much.

The pa21 maximizes all our efforts with more power, more dynamics and greater flexibility. The full-sized chassis allows us to use larger transformers and bigger caps and resistors, delivering greater control and detail.

The result is 55 watts of pure pentode output per channel, and improved stability throughout the amplifier. We do implement a very modest amount of global negative feedback to make the amp rock solid.

With more room at their disposal, our engineers continued to search for improvements, such optimal efficiency, the lowest signal degradation and the greatest immunity from noise and hum. They accomplished just that, with carefully separated and laid-out signal ground, power supply ground and chassis ground schematics.

We've also advanced our proprietary Adaptive AutoBias board with a special circuit that re-calibrates it for EL34s or KT88s. One flick of a switch allows you to run either tube at its optimal level. And as always, the board continuously monitors each tube, tweaking it to its sweet spot. There's no biasing, no need for matched tubes, no worries.

Combine the pa21 with its matching full-size ca21 preamplfier, and experience a truly reference-quality system, without a typical reference-quality price tag.
