Ultra RCA Interconnects transfer the richness, authority, and spaciousness of the best music sources in ways other RCA cables in the same price range can not approach. Every length of Transparent Ultra RCA Interconnect has its own network design calibrated for that specific length and type of cable so that all the Ultra cables in a system perform at the same level, regardless of their individual lengths. Ultra networks and cable work together to reject noise for cleaner, clearer, more focused signal transmission. Ultra transfers audio signals more efficiently and over a wider range than Super, resulting in greater musical impact and realism. Ultra works exceedingly well with virtually any type of system component so they do not require factory calibration when changing system components.
