RCA single-ended connections are almost universal and differ from balanced connections in that rather than three conductors (plus/minus/ground) there are only two (plus/minus). Ground and shield are usually tied to the negative outer barrel at the load/receiving end of the interconnect cable. Using our exclusive RCA connectors, high-purity, Laboratory-grade copper conductors, low-capacitance dielectrics plus superior shielding, our single-ended cables produce fast, natural and what some feel are single-ended’s greatest strengths: a slightly more extended and lively sound with tighter bass than balanced connections. As with our XLR cable, moving from Entry to Top Level brings increasing clarity and transparency, tighter and more controlled bass, better sound-staging, and better detail retrieval in the midrange and highs.
