Issue 1 The Mains Power Supply

​

We consider the mains as inadequate a source of power for the audio equipment of the resolution that we are aiming the mains power supply for

Today, the loads that are connected to the mains are more and more of the non linear type, which dramatically lowers the power and energy transfer to audio circuits. This has a dramatic impact on sound

​

That is why we have invested time and money into battery power solutions, being very well aware of the fact, that many battery powered amplifiers do not necessarily sound good

It turned out that we had to engineer the preamplifiers, amplifiers and front ends to suit the battery’s technical specifications.

​

This mainly led to solid state devices , while we did not refrain from fully battery driven tube equipment, although those may be too big in size, in weight and in budget for many.

The latter have to be understood as research objects showing how far one can go with tube circuits, once they are freed from the mains problem
