A$22,000 is a strong bargain for an Audionet STERN preamp, sitting well below the typical used market where the last known listing reached A$29,000 against an original retail of A$73,500.
The STERN is a revered German reference linestage known for its microprocessor-controlled ultimate linear design, delivering ultra-low noise (>123dB SNR), negligible distortion (<0.004% THD+N), and a colossal 0–2.2MHz frequency response. At this price, you’re acquiring a top-tier preamp that pairs with flagship power amps like the HEISENBERG, offering rarity, proven performance, and significant upside for a collector or serious listener—especially if it’s original-owner condition with accessories included.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Audionet emerged in 1994 from the innovative labs of Ruhr University in Bochum, Germany, where founder Thomas Gessler and fellow electronics researchers developed cutting-edge sensor and measurement amplifiers. Born from a decade of work on low-noise, high-resolution analog circuits for scientific applications, the company—initially Idektron & Co.—launched its first sensation, the Audionet preamplifier, translating to "sound network." All products are designed and handcrafted in Germany, with roots later shifting to Berlin, embodying a rigorous scientific heritage that prioritizes precision engineering over convention.
The brand excels in high-end solid-state electronics, spanning preamplifiers, power amplifiers, monoblocks, integrated amps like the Humboldt, phono stages, CD/DVD players, network components, and external power supplies. Signature technologies include the Ultra-Linear Amplifier (ULA), originally engineered for medical use, ensuring ultra-pure signal paths via custom miniaturized components. Industrial design by Hartmut Esslinger—creator of the Apple IIc—elevates models like the Scientist Series Stern linestage and Heisenberg monoblocks, blending functionality with award-winning aesthetics.
Audionet commands reverence in the ultra-high-end market as a reference-level boutique, setting benchmarks for transparency, power, and stability that audiophiles worldwide anticipate as events. Handmade in small batches, its electronics deliver uncompromised performance for discerning systems, from stereo purists to advanced home theaters, backed by a global reputation for pushing hi-fi boundaries with scientific rigor.
