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.

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.
