AudioQuest 's Big Sur mini cables feature Perfect-Surface Copper+ (PSC+) conductors and gold-plated pure "Purple-Copper" RCA plugs for a marked sonic improvement over standard mini cables. While theoreticians debate whether the true nature of the universe is analog or digital, one constant in our audiophile galaxy is that the music, dialogue, and sound effects which reach our ears is analog. In order to preserve this precious cargo, AudioQuest has designed a range of analog interconnects optimized for the single-ended world. Big Sur takes advantage of years of carefully balancing design and material selection in order to bring you a series of interconnects which, as much as possible, "Do No Harm" to the original audio signal. Solid Core Conductors Big Sur , like virtually all of AQ’s cables, uses solid-core conductors for the analog pathway. Solid-core conductors are more efficient at transmitting small signals than stranded cables and are also vastly lower in distortion, a difference that is clearly audible from the first instant; the system sounds like someone turned up the volume! This efficiency also translates to more music coming through, plug in a Big Sur and hear things in your music you’ve never heard before. Perfect Surface Copper + (PSC+) Big Sur receives AQ’s best copper, PSC+ . A higher grade of copper than PSC, PSC+ receives the same proprietary Perfect Surface polishing process which, as the name implies, smoothes the surface of the conductors. Since treble and midrange frequencies travel very close to the surface in a solid-core conductor, eliminating even microscopic roughness on the surface of the conductor greatly reduces distortion. Sonically, PSC+ is vastly more resolving than PSC, like lifting a sheet off of the speakers, offering greater resolution, greater presence, far more extension top
In all Bridges & Falls, you¡¯ll find better metals and more sophisticated technologies — including Air-Tube insulation, Dielectric-Bias System, and Noise-Dissipation System — at lower prices than ever before.
