Know before you buy
The Foundation SX is designed to lower your system's noise floor, which allows for greater resolution and a more natural, lifelike timbre. By utilizing technology from the flagship SRX line, it improves overall dynamics and provides a sense of immediacy to the music.
The Carbon Tuning Discs are used to fine-tune the cable's performance by further refining noise cancellation. You can experiment with their placement to adjust the soundstage presentation to better suit your specific listening environment.
This cable features doubled 6N pure silver Air Strings and advanced SRX XL UEF shielding, which are significantly more sophisticated than standard power cables. Additionally, each cable undergoes a high-voltage conditioning process to optimize electron flow for better performance right out of the box.
Yes, this cable uses a standard NEMA 5-15P input and a C13 IEC output, making it compatible with most high-end audio components. It is rated for 125V and supports up to 20 amps, ensuring it can handle the power requirements of most amplifiers and source components.
While the cable undergoes SRX XL High Voltage Conditioning during manufacturing to ensure optimal performance, like most high-end audio cables, it will continue to settle and reach its full sonic potential after a period of regular use in your system.
The cable utilizes a double-shielded design incorporating SRX XL Matrix shielding, UEF coating, and Graphene. This combination effectively blocks electromagnetic interference and radio frequency noise, which is essential for maintaining a clean, quiet signal path.
