AudioQuest Yosemite RCA > RCA with DBS(72v) Audio Interconnect Cable Connect a wide range of audio electronics with this AudioQuest Yosemite 2-Male RCA analog interconnect, meticulously designed for outstanding flexibility and versatility. Solid Perfect-Surface Copper+ (PSC+) conductors minimize distortion, FEP Air-Tube insulation preserves dynamic contrasts, and a Carbon-Based Noise-Dissipation efficiently dissipates high-frequency noise for cleaner, clearer, more naturally beautiful music. Solid Perfect-Surface Copper+ (PSC+) Conductors Solid conductors prevent electrical and magnetic strand-interaction. PSC+ Solid-Copper minimizes distortion caused by grain boundaries and maximizes linear RF Noise-Dissipation. Carbon-Based 3-Layer Noise-Dissipation It's easy to accomplish 100% shield coverage. Preventing captured Radio Frequency Interference (RFI) from modulating the equipment's ground reference requires AQ's Noise-Dissipation System (NDS). Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical "reference" ground plane, which in turn causes a distortion of the signal. NDS's alternating layers of metal and carbon-loaded synthetics "shield the shield," absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground. 72v Dielectric-Bias System (DBS) All insulation between two or more conductors is also a dielectric whose properties will affect the integrity of the signal. When the dielectric is unbiased, dielectric-involvement (absorption and non-linear release of energy) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a real problem for very time-sensitive multi-octave audio. The inclusion of an RF Trap (developed for AudioQuest’s Niagara Series of power products), ensures that radio-frequency noise will not be induced into the signal conductors from the DBS field elements. (DBS, US Pat #s 7,126,055 & 7,872,195 B1) FEP Air-Tube Insulation Positive conductors benefit from almost no contact between metal and its FEP insulation, which is notable for its superior dielectric constant and minimal signal interference. Negative conductors benefit from intentionally “lossy insulation” — no air and no FEP helps maximize the negative connection’s different job. Asymmetrical Double-Balanced Geometry Purpose designed for single-ended applications, Asymmetrical Double-Balanced Geometry offers a relatively lower impedance on the ground for a richer, and more dynamic experience. While many single-ended cable designs use a single path for both the ground and the shield, Double-Balanced designs separate the two for cleaner, quieter performance. Cold-Welded, Direct-Silver Plated Pure Red Copper Terminations Direct-Silver Plating is optimized for sound, using no underlying layer of distortion-causing nickel, while the highly effective cold-weld process avoids sound-degrading solder. The DBS module has some tape and shows signs of wear but this does not affect the sound quality in any way. Used to connect the Marantz SA7003 with the Marantz KI Pearl Lite amplifier. Used and private sale, returns won't be accepted as there is no warranty on it but can promise good packing for shipping
