The company AcousticPlan was founded in 1996 by the German music enthusiast Claus Jäckle after fifteen years of experimental research on music reproduction and its complement, i.e. issues of recording and acoustics. This new venture was moved by the thrust to realize very special and unusual ideas. The production of highest quality music components requires today, not only innovative design and professional engineering skills, but also a devotion to craftsmanship and the relentless pursuit of perfection.
All AcousticPlan products will always be the manufactured according to the highest standards of masterly German engineering. AcousticPlan’s high end components excell by their visual attraction and acoustic signature. The integration of superior components, e.g. special broadband drivers,signal transformers of our own development or circuits in hybrid technique far-off any mainstream, supports the design. The development and production of AcousticPlan music components involve people with different professional backgrounds ranging from engineering to product design and musical performance. All of them are fascinated by the art of music reproduction and devoted to continue the great tradition of a German engineering.
Why hybrid technique?
The endless quarrel about whether a tube or a transistor will yield superior sound results will never be definitely settled. But much more important than a special device (whether tube or transistor) is their integration in the circuit. Electronic components should never be evaluated as isolated parts. They are elements of a circuit that works as a whole. The pleasant and typical sound of tubes depends on their transfer characteristics. Any circuit design has to account for this. AcousticPlan uses transistors therefore only for those parts of the circuit where their parameters are superior to those of tubes: at MC Phono input (PhonoMaster) and at the power stage just for impedance converting.
Thoughts and opinions:
The highest aim of any electronic engineering is to reproduce the original sound as authentical as possible. A closer look, however, will discover that this aim can only be realized approximately and in an illusionary way. Neither the acoustical conditions of a concert hall nor the position of the listener’s seat can be reproduced acurately. If the recording is done via multi mic arrangement the reintegration of the various tracks doesn’t have much in common with the original concert hall experience.
Therefore the aim of music reproduction should be the recreation of musics emotional experience. To realize this high ambition we have to pay attention to other parameters than those that yield superior technical data. AcousticPlan efforts thrust for this recreation of the essence and the spirit of music. AcousticPlan music components were designed to get as close as possible to this ideal of emotional experience. This is achieved by an effortless reproduction that allows for a relaxed, but involving encounter with the musical event. Neutrality and harmony of sound without overly extended high and low frequencies do not exclude the fascination of the live experience. Excessive sound at the frequency extremes diverts attention from the essence of music and may even result in confusion.
Therefore AcousticPlan components are geared to the reproduction of the mid frequency range where the human ear is most sensitive and where voices as well as instruments have their highest intensity. AcousticPlan loudspeakers use consequentially broad band chassis with an extreme light diaphragm for the reproduction of the entire low mid to high frequency range. Paradoxically the increasing high range directivity of the broad band chassis improves the clearness of representation – an effect that is usually achieved by adding high frequency energy. But this technique has its side effects: it results mostly in a nervous and harsh rendition of the music.
Sound engineering commonly centers the accurate reproduction of instrumental focus (not to mix up with spatial reproduction). The resulting image differs, however, strongly from the live concert experience. When we are closing our eyes in a musical concert we are hardly able to identify the separate sources of sound. Much more important than instrumental focus is the re-production of sound space in its three dimensions. The adequate imagination of the spatial dimensions and the stability of these dimensions are one of the areas where broad band speakers excell because of their correct phase response. Recreating the emotion of the life musical experience requires a certain sweetness of sound. This much cherished quality of music reproduction depends on special technical parameters such as the spectral distribution and the degree of harmonics, furthermore less difference tone distortion. Speakers as well as amplifiers – regardless with a tube or transistor – have their part in producing these effects. Here, too, the circuit design is of paramount importance. A minimalistic design is usually superior to complex feedback amplification. Therefore AcousticPlan amplifiers are constructed with the least possible numbers of active stages.
