Preamplifiers Audionet Stern

The machine:

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.

The patented FLOATING PANE DESIGN encorporates the ultimate audiophile qualities.

One amp to rule them all – STERN rises high above anything, anywhere – even our serial show winner PRE G2 (2015 “best sound” at RMAF, AXPONA, T.H.E.SHOW and HIGHEND).

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.
