Introduction:

Through the years, much improvement has been accomplished as to the quality of our audio systems. Cables, resistors and capacitors have less sound-degrading effects, certain types of distortion products have been decreased or eliminated and better, less resonant, materials are used in record players and loudspeakers etc. Despite all this progress we are still commonly lacking some of the realism of a live concert. Modern hi-end systems have far less coloration's but are normally not capable of reproducing the presence and the sheer power and dynamics of the real thing. We want our systems to be able to reproduce both the delicacy of natural instruments combined with the dynamic contrasts of powerful music. In this regard, further improvements can be accomplished - not only to our loudspeakers but also to the associated electronic equipment.

It is well-known that interconnects, capacitors, coils, resistors and active devices all can have large audible effects of their own. These distortions are kept as low as possible by 1) careful circuit design, 2) high quality parts and 3) a minimal number of components. As far as our design philosophies are concerned, there is no such thing as "euphonic distortion". Any kind of sonic imprint of the audio signal, regardless of what it sounds like, must be avoided/minimized! It is the source to an audible effect that must be dealt with, not the symptoms. Sonic tuning, of for example a dull sounding amplifier, by adding some spicy sounding component only ends up in a mix of two wrongs.

Electronic design

If we want everything: live dynamics and low coloration etc., then a consistent non-compromise approach must be applied throughout the entire chain of audio equipment. Herein lies a contradiction because there is nothing that is perfect. So, the question arises as to which technical solution should or must be used in each specific application and then try to improve upon their individual drawbacks. There are many applications in our audio systems where important parameters can best be achieved by only one or a few technical alternatives and then these must be chosen as the route to go and serve as basis for further technical development. Then we can hopefully get the best of both worlds without "compromises".

It is sensible to use a technical solution which is best suited for each special application and purpose. This approach assures a high quality and efficient use of the parts and thereby also has the spin-off-effect of minimization of construction complexity which in itself has the advantage of fewer sound-degrading components. Why use a preamplifier with say 20 dB of gain if your system does not need this extra amplification at all. Why use a non-linear transistor for voltage gain when it can be replaced by a less distorting tube and as a consequence eliminate negative feedback. On the other hand, a transistor is better suited for power amplification and does not need any sound degrading output transformer. Various technical solutions have their merits and weak points. Equipment design involves a balance of seeing which technical solution must be used in a certain application and in recognizing it's potential and possibilities for improvements.

By designing a circuit as simple as possible, we are actually demanding more from these fewer devices. If, for example, an amplification section is to work properly without the help of a following buffer stage, then we have additional demands for lower output impedance of that amplifier. A combination of high amplification and low output impedance from the same device is not so easy to accomplish, but this example serves to illustrate our design philosophies. We technically develop to be able to simplify the designs. Our end goal is to achieve a high level of sonic accuracy and in this regard, simplest is not necessarily the best. In addition to technical, there are also economical aspects. Eliminating printed circuit boards is technically easy to do but the alternative hard wire technique is more time consuming and costly in fabrication. The audible benefits, however, are well worth it so that is what we do!
