Audiophiles need to understand that the primary element in their setup is the power cord. This initial component must be free from distortion and capable of efficiently carrying large amounts of current and voltage to the device. It's acknowledged that the musical signal originates from the AC wall outlet in the form of voltage and current, and the device simply transforms this power into a musical waveform. Standard power cords that come with most devices may introduce distortion or degrade the signal quality. Therefore, it's essential to use a high-quality, non-reactive cable; once the signal is compromised, it's irreversible, regardless of the quality of subsequent components.

The Ultra Line stands out among other lines due to its incorporation of MasterBuilt insulation and advanced winding geometric technology. Its significant advancement lies in the use of conductors crafted from a proprietary alloy of precious metals. This exceptionally pure transmission path ensures a distortion-free signal delivery to your electronics, resulting in a remarkable dynamic range and exceptional resolution of fine details. Integrating Ultra Line power cords into a system allows listeners to discern details they've never heard before in their reference recordings. Undoubtedly, Ultra Line power cords represent the pinnacle of quality and are reserved for only the most elite audio systems.
