The Goldmund Telos 3300 Nextgen Amplifier is a 700 watt Universal Mono Power Amplifier, made by the high end Swiss Hifi brand.

The Telos 3300 Nextgen circuitry is the latest enhancement of Goldmund’s 30-year old circuit. Several R&D developers have added layers of evolution to this schematic.

The amp has the traditional Goldmund solid brass structure and metal finish applied to the aluminum external surfaces, that make the Telos 3300 Nextgen a piece of sculpture as well as an amplifier.
