AudioQuest Sydney

AudioQuest Sydney Interconnects 1.0 m pair  
These are brand new, never used cables.  I've had them just one year but never ever used them.  I acquired something else that I used instead and never even tried these.  I thought about keeping these, which is why I've had them a year.  I figure I would eventually use them but would rather get some money instead.
  

Sydney Spans Greater Distances Than Much More Costly Cables AudioQuest 's Sydney interconnects feature Perfect-Surface Copper+ (PSC+) conductors and an insulation system built around Polyethylene Air-Tubes for a marked sonic upgrade over standard interconnects, improved dynamic response, and a truly uplifting listening experience. 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. Sydney 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 Sydney , 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 Sydney and hear things in your music you’ve never heard before, literally! Perfect Surface Copper + (PSC+) Sydney 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.
