The Heart of Goldmund

At its heart lies Goldmund’s proprietary Telos® amplification technology: a Class A/B circuit architecture honed over 40 years of research and development to achieve ultimate linearity, wide bandwidth, and ultra-low distortion. This advanced design ensures pure, uncompromised musical reproduction—even at demanding power levels.

Sound, Pure and Dynamic

Harmonic and intermodulation distortions are virtually eliminated, while the amplifier’s wide-bandwidth circuitry preserves timing, dynamics, and spatial accuracy. The device’s dual-circuit architecture separates low and high-current paths to eliminate interference and maintain signal purity.

Many of the Telos 670’s critical components are designed and manufactured exclusively for Goldmund. These bespoke elements—unavailable elsewhere—embody our dedication to sonic purity and engineering excellence.

The Goldmund Code

Goldmund’s sonic philosophy is founded on the following principles:

Near-zero harmonic distortion
Near-zero intermodulation and TIM distortion
Near-zero vibration and mechanical resonance
Exceptionally high dynamic range
Absolute thermal stability
Virtually silent background
