RIP Gibraltar, long live Castle Rock! Like Gibraltar before it, Castle Rock is designed as an extremely high-performance cable which provides true Double-BiWire performance in a single attractive cable. Original Gibraltar’s all important basics – superior geometry, magnetic autonomy of each quad-conductor section, Perfect-Surface metal technology, conductor-size optimization (AQ’s Spread-Spectrum Technology), etc. – are the fundamentals of Castle Rock. Castle Rock employs AQ’s best copper conductor metal (Perfect-Surface Copper+), AudioQuest’s DBS (Dielectric-Bias System) and NDS (Noise-Dissipation System).
A very recent advancement featured in Castle Rock (and all other Tree and Rock Series speaker cables) is the addition of the sleek new “Hanging-Silver” 1000 Series Multi-Spades and Bananas. Originally developed for the WEL Signature Series speaker cables, these plugs are made using a “hanging silver over pure red-copper” process in which the spades and bananas are submerged (“hung”) into a vat of extreme-purity silver, resulting in a very thick direct-silver plate. No intermediary performance-degrading materials (such as nickel or alloy) are used.
Also new to Castle Rock is a more-neatly-sculpted “breakout” (the covering where the cable separates into red and black legs), which is now made of a synthetic non-magnetic polymer, rather than metal. We’re making this all-models upgrade because speaker cables and AC power cables carry large magnetic fields which interact with any metal “collar” around the cable. Eliminating metal in the breakouts is another significant (and clearly audible) step forward in our goal of eliminating distortion and making the cable sonically “invisible.” Please note too that AudioQuest now offers a Single-BiAmp option for any Rocket, Flat Rock or Tree Series speaker cable, including Castle Rock. Although similar to a Single-BiWire configuration in which the speaker end has four connectors, the Single-BiAmp configuration also has four connectors at the amplifier end to accommodate the growing number of users who wish to take full advantage of all the amplifier channels in many of today’s AV receivers and multichannel power amplifiers.
Castle Rock represents the culmination of Gibraltar’s long-term evolution along with performance- enhancing new systems and materials. These ingredients add up to important audible improvements and more pleasurable listening!Visit Audioquest for specifications
