Crafted with meticulous attention to detail, the Telos 690 exemplifies Goldmund’s commitment to precision mechanics. Its upgraded panel structure not only reinforces the amplifier’s enclosure but also enhances mechanical grounding and vibration dispersion capabilities, elevating every interaction with the amplifier into an extraordinary sensory experience.
