Speaker control is exerted in two ways: by giving them enough power to produce high-quality and undistorted sound; and by controlling the drivers better preventing them from producing parasite sound. This is especially true in low frequencies where drivers’ range of to and fro movement is higher, increasing the likelihood of unwanted sounds that affect the purity of the signal. Telos^® amplification technology significantly reduces the intermodulation by improving the linearity of all stages and considerably decreasing the time distortion. Based on Leonardo^® research program, the Telos^® uses a higher bandwidth circuit with minimal group delay distortion inside the audio bandwidth. Telos^® amplifier input circuitry includes the latest version of Alize Digital/Analog converter circuits for enhanced coupling with Goldmund Universal Preamplifiers. Separate input and output stages prevent feedback between high and low current circuits and improve the Mechanical Grounding™. One of the most important sonic improvements provided by the latest Telos circuit is its «driver control». Obtained by lowering the output impedance of the amplifier to an extreme degree, it provides a much higher quality of micro-dynamics and helps large woofers overshooting and delivering a boomy bass. Telos^® amplifies the audio signal with incomparable purity and transparency whatever the volume, without distortion.
