Mystere

While the brandname Mystère might sound new to you, the company behind it, is NOT. Since 1975 our company Durob Audio in The Netherlands is active in the field of high-quality, high-end audio equipment.  Our activities can be found in representing high-end manufacturers in BeNeLux, distributing and servicing their producs to local dealers, offering high-end products at retail in our own high-end oriented retailshops and last but not least designing, manufacturing and distributing our own range of products.

 Philosophy:  More than 30 years of working almost day in, day out with audio products of highest quality, results in the simple fact that the only quality level accepted is the best possible in whatever price range you can think of.
 
This you will always find back in our products we bring to market, but also in the after sales service which you might need one day. We dare to say our reputation is of the highest and we intend to keep that, even if that is maybe no longer 'modern time philosophy'.
 
We also always try to explore new ideas. We were first (and only?) to fluid-damp (with conductive gel) single strands in our Cogelco cables, came up with Adaptive (this is most important of it) Auto Bias circuits for tube amplifiers, used super polished diamond styli in our Kiseki cartridges from day one and have recently introduced a first (and unique) SuperTubeClock (yes, that's correct a clock with a heart of tube) which can be used in our famous upgradable AH! Njoe Tjoeb cd players and every other cd, dvd, sacd player out in the market.
 
Much can be said about what we did and what our plans are, but in short we will always bring you better and best quality of product and support at whatever pricepoint -from the lowest to the highest-.

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.
