Audionet STERN


Designed by German design legend Hartmut Esslinger of Cupertino fame, our new über-performance preamp STERN combines Audionet’s unique electronics, stratosphere version, with a design quality that has not been seen in the realms of highenddom before.

Special features STERN

  • Magnetically and capactively optimized circuit and device design without any ferro-magnetic materials.
  • Floating Pane Design for optimal resistance against microphonic effects and temperature stability.
  • The floating panels of the body are resonance-optimized by pads on an aluminum frame.
  • Mounting and bolted assembly of transformers made of stainless steel.
  • Double mono layout of circuitry and power supply for maximum channel separation.
  • Air Flow Design circuit boards for an optimum of cooling and stable quiescent currents.
  • Galvanic separation of all analog circuits by opto couplers.
  • The input and output sections as well as the volume control are implemented using enhanced, discrete Audionet operational amplifier modules with state-of-the-art mica capacitors.
  • Rhodium Cinch jacks by Furutech.
  • Volume controller on a double ball-bearing axis and with magnetic ratchet and optical sensing.
  • Volume controlled by electronic switches and real-time linearized precision resistor network.
  • DC coupled with no sound diminishing capacitors or coils, shortest signal paths.
  • One separate transformer per channel for the positive and negative half wave, leading to the perfect power supply.
  • Four encapsulated and decoupled 50 VA toroid transformers.
  • Main power supply capacitors 22,000 µF, optimized for very low impedance and made with silk dielectric.
  • Total capacitance of 176,000 µF.
  • Microprocessor control with separate power supply monitor and control of all functions, informing the user on a high resolution display.
  • By-Pass mode for integration into home cinema systems.
  • Audionet Link outputs for the remote control of further Audionet devices.
  • User definable names for each input, input levels adjustable for each input.
  • User selectable function to remove DC levels from signal sources.
  • Rhodium fuse.
