Features Gold RCA Termination Compacted Cert.Copper CDA106 Super Foam PP and PTFE Insulation ADVANCED HELIX Design Clear Over Silver-Black Braid Jacket Description Product Description Straight Wire has introduced an improved version of their highly acclaimed Crescendo Interconnect with significant advancements. The CDA certified premium conductors are now compacted with 6% compression instead of 3-4%. This advancement in Compressed Conductor Technology (CCT) technology greatly improves upper midrange and higher frequency transmission. The dual layers of microporous foam PTFE insulation are increased and the outer dielectric of foamed Polypropylene is slightly decreased to further refine presentation throughout the audio spectrum . Due to the large advanced helical design, the soft PTFE inner layer of insulation would vary in dielectric dissipation effects and consistency if not encapsulated with a thin layer of form Polypropylene. Ultra-low conductor group resistance remains the same - 12 groups at 21 awg. Greater upper register spatial cues and 3 dimensional airspaces together with low level details and unmatched dynamics are easy to discern with this cable. Mid and Lower registers are effortlessly portrayed with remarkable spatial coherence and controlled yet captivating engaging authority. It synergizes reference caliber components to provide remarkable, memorable performances.
