Telos 690
Integrated Amplifier
A World of Sonic Possibilities
The Telos 690 integrated stereo power amplifier was conceived to provide an audiophile-grade amplification option that embodies Goldmund’s iconic sound signature. Designed for those who seek exceptional performance from their analogue sound system in simpler system setups, the Telos 690 meets the highest standards in a simplified configuration.
The Heartbeat of Innovation
What sets our amplifiers apart is our proprietary Telos® amplifier technology, first introduced in the 1990s and continuously refined since. Telos® amplification operates in Class A/B, utilizing highly linear analog components combined with a high-bandwidth circuit.
Your Gateway to Sonic Bliss
Telos® amplifiers exert precise control over speaker drivers, delivering clean, ample power while preventing unwanted noise that can compromise signal integrity. This control is especially critical in low frequencies, where woofer diaphragms exhibit greater movement, increasing the risk of distortion and unwanted vibrations. By drastically lowering output impedance, Telos® enhances micro-dynamics and prevents large woofer overshoots during high-power conditions—eliminating uncontrolled bass and maintaining absolute sonic transparency.
The Hi-Fi Standard
Unlike many amplifiers that lose clarity or introduce subtle distortion at lower volumes, Telos® ensures sound remains perfectly transparent, detailed, clear, dynamic, and virtually distortion-free across the entire frequency range. Whether playing at a whisper or full concert intensity, it faithfully reproduces the purity of the original signal—without compromise.
Telos® significantly reduces harmonic and intermodulation distortions by optimizing linearity in each amplification stage. By isolating high and low-current circuits, it prevents unwanted feedback and interference while improving Mechanical Grounding™.
Audio Mastery in Every Note
The amplifier features our new power supply unit (PSU), redesigned for greater efficiency, higher power output, and a new power supply board providing greater energy reserves. A smooth transient response between low and high sonic levels enhances dynamic range and allows precise handling of rapid volume changes. Capacitor power banks were specifically tailored for stereo amplification.
Advanced Acoustic Engineering
At Goldmund, technical perfection and exceptional listening experience are inseparable—neither is ever compromised. Unlike conventional amplifiers that perform well with resistive loads in lab conditions but falter when driving real-world passive speakers, Goldmund amplifiers maintain sharp performance in both scenarios. This ensures absolute control, precision, and musicality—faithfully translating every nuance of the audio signal into an unparalleled listening experience.
Elevate Your Ears
While our extensive experience confirms a strong correlation between superior technical specifications and outstanding sound quality, we go beyond theory. Our testing protocols rigorously validate both objective measurements and listening impressions. By refining the measurable and perceptual aspects of sound reproduction, we ensure every Goldmund amplifier is not only flawless in specification—but extraordinary in real-world performance.
Engineering You Can Hear
Our mechanical design is equally exceptional, combining precision engineering with aesthetic refinement. The ultra-thick chassis is crafted from a unique micro-blasted aluminum alloy, resulting in a smooth, silk-like finish. Its seamless assembly—with no visible joints and minimal screws—ensures both structural integrity and visual elegance. The Conic Feet, designed according to our mechanical grounding principles, evacuate unwanted vibrations to the ground, preventing resonance buildup and preserving signal integrity.
Beyond aesthetics, our mechanical design is purpose-driven, addressing critical technical requirements such as heat dissipation, mechanical grounding, and electromagnetic shielding.
Soundscapes Redesigned
Goldmund sound is defined by clarity, transparency, dynamic range, and uncompromising purity and fidelity. It is through this relentless pursuit of innovation that we continue to evolve Telos®—delivering an audio experience that reveals the original recording as faithfully and powerfully as possible.
