Audionet Humboldt Integrated Amplifier

Conceived and built by Audionet and designed by the legendary German industrial designer Hartmut Esslinger, the HUMBOLDT combines the outstanding qualities of the globally acclaimed series show winners STERN and HEISENBERG in an integrated amplifier the likes of which the world has never seen before.

Ultra Linear Amplifiers

Each channel has its own transformer on the Humboldt. The secondary windings always supply the analog and the control unit separately, mutual interference is excluded. Elko banks with the performance of small power plants are available for intermediate storage of the energy. With Audionet's proprietary "Ultra Linear Amplifier" technology, the signal runs through the input and output stages over the shortest possible path for ideal impulse response. Phase- and impedance-critical loads can be driven without a drop in stability, the distortions are at a level that is practically unmeasurable.

music transport

If the music is not transported on the circuit board, it takes place via gold-plated pure silver lines. A number of the components used, for example the mica capacitors, are also manufactured with exact specifications for Audionet, as are the noble Furutech rhodium terminals and the fine-wire fuses with a thread made of the same material.

volume control

The volume can be controlled in around eighty steps, the level setting is recorded without contact. The optocouplers used have the advantage that there is no electromagnetic interference as with a conventional potentiometer. The actual level is then set via a network of metal film resistors.

Cleanest electricity in the world

The trick of only working with the cleanest electricity in the world - the one that comes from gallium arsenide LEDs - not only ensures incredibly good, unique sound, but also a unique red light inside an Audionet amplifier. This is not decoration, this is systemic!
