Goldmund Telos 670 – Swiss Integrated Amplifier

26.09.2025 05:00 | ~1 minute read

Goldmund presented the Goldmund Telos 670 integrated amplifier – the device operates in class AB and produces 2 x 250 watts of power when working on a load with an impedance of 8 ohms. The Goldmund Telos 670 implements the patented Telos amplification technology, providing a wide bandwidth and extremely low distortion. Due to the reduction in the output impedance of the amplifier, the bass response has also been significantly improved.

In terms of switching, the Goldmund Telos 670 includes five unbalanced analog line inputs, plus three digital ones, including an optical Toslink port, a coaxial S/PDIF input, and a USB-B port. The built-in DAC is capable of receiving streams in PCM format with a resolution of up to 32 bits / 384 kHz, as well as DSD up to DSD128.

The device's body is assembled from 10mm and 30mm thick aluminum panels - which ensures absolute thermal stability without the need for active cooling. The new chassis structure and conical feet effectively conduct vibrations away from the internal electronics.

The Goldmund Telos 670 integrated amplifier is already available in micro-blasted gray and black color at a recommended retail price of CHF 20,000.
