Audionet HUMBOLDT
HUMBOLDT is Audionet’s Scientist Series integrated amplifier, carrying the technology of STERN and HEISENBERG into a single chassis.

What Audionet says
Audionet built HUMBOLDT to share the qualities of STERN and HEISENBERG, the preamplifier and monoblocks it sits beside in the Scientist Series. Hartmut Esslinger designed the casework, and inside is what Audionet calls the most advanced circuitry and technology available in high-end audio today.
Every circuit and the power supply are laid out in double mono for maximum channel separation. Audionet’s own verdict: an integrated amplifier unlike any other on the planet.
What reviewers say
“Audionet’s Humboldt integrated amplifier isn’t just a reference-level integrated amplifier; it’s a statement-level integrated amplifier.”
Hans Wetzel, SoundStage! Ultra
“In the universe of expensive integrated amplifiers, HUMBOLDT sits amongst its peers as a primus inter pares device of extraordinary ability.”
