Telos 2500

Telos 2500 - Power Amplifier

The Telos 2500 is born out of the alliance of the Telos 600 and Millenium amplifiers. It includes the incredible accuracy and power of the Telos 600 and the exact mechanical construction of the famous Millennium amplifier. The Telos 2500 has the same dimensions and finish as the Millenium amplifier, except for the front screen.

The Telos 2500 has been designed to provide much more power on low impedance speakers. It offers both dynamics and transparency and easily handles the most demanding audio applications.

Its circuit time accuracy is unique, with more than 100ps. It uses a high bandwidth circuit with minimal group delay distortion, taking great care of the cut-off distribution nodes so the group delay distortion is not measurable inside the audio bandwidth.

This mono amplifier includes the Alize technology with an Alize 6 input D/A converter that improves linearity and static protection.

With 12 separate high-power transformers, 2 separate low-power transformers and a separate power supply for the safety circuitry, the Telos 2500 is one of the safest amplifiers on the market. It benefits from a three-year labor and parts warranty.
