Absolute Control, Pure Sound

Goldmund’s Telos® amplifiers deliver pure power with absolute precision, ensuring the audio signal remains pristine. Proper driver control eliminates distortion and unwanted artifacts, particularly at low frequencies, where excessive woofer motion can introduce unwanted vibrations. By refining every stage of amplification, Telos® technology eliminates harmonic and intermodulation distortion, while its high-bandwidth circuit ensures impeccable sonic coherence. By isolating high and low-current circuits, it prevents feedback and interference for an accurate audio transmission.

Mastering Every Decibel

A sophisticated output impedance reduction system enhances micro-dynamics, controls excessive woofer overshoot under high power, and removes unnatural bass bloom. Despite its impressive output, the Telos 1800 delivers flawless performance from the first watt—whether playing a soft piano passage or a full-scale orchestral crescendo, the sound remains dynamic, detailed, and distortion-free.

Elegance in Engineering

The Telos 1800 embodies the perfect fusion of high-end technology and aesthetic sophistication:

Seamless Aluminum Chassis: Sculpted from a single block of micro-blasted aluminum, the chassis is a study in both strength and grace. Its uninterrupted, joint-free chassis is offered in a timeless grey, with a black finish available upon request. Gently undulating sides echo Goldmund’s evolving design language and lend the piece a mineral allure and a natural harmony with every other device in the collection. A golden accent ring crowns the top panel of units destined for the Chinese market, while matching grey rings complete the silhouette for all other markets, ensuring each version remains true to its essence.
Advanced Electromagnetic Shielding: The solid aluminum housing acts as a fortress against electromagnetic interference (EMI), ensuring a pure signal path.
