We are now fully open, but due to Covid 19, we are taking the precaution of asking for demos by appointment only, to arrange your appointment please call us 01592 859163 or email

We are maintaining social distance and the premises and equipment is cleaned regularly and between appointments.

Audionet STERN

£35,000.00

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.

Description

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).

“Surpasses the performance I’ve heard from any solid-state players at any price.” Greg Weaver, The Absolute Sound

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.
