Monster's Ultra Series is a result of hundreds of hours of critical listening, testing, re-evaluation, and engineering refinements. Only the most advanced Monster technologies, designs and materials were used. And of course, every cable had to meet the stringent certification standards set by THX. As you'll see and hear, the results are ultra impressive.DVD Audio and Super Audio CD (SACD) are some of the highest quality sources available today. How many analog cables you need depends upon the format. DVD Audio, for example, requires six channels of analog audio outputs connecting to a proper AV receiver which has six channels of audio input.Whatever high resolution Audio format you use, Monster Ultra Analog Audio cables ensure that the accuracy and dynamic impact of the original signal is captured with more realism, more power, and amazing clarity. Leading edge technologies include Bandwidth Balanced multiple gauge wire networks for meticulous frequency response and elimination of phase distortions and time smear. The result is an exceptionally balanced, coherent sound.PRODUCT FEATURES: Multiple gauge wire networks for accurate, natural sound reproduction; 12-cut Turbine 24k gold contacts for a superior connection; Exceeds THX certification standards for proper system performance, reliability and ease of installation; Bandwidth Balanced design for increased clarity and sonic accuracy; MicroFiber insulation for deeper, tighter bass and clearer highs; Silver content solder joints for high conductivity connection that accurately transfers low level signals; PEXTM dielectric insulation provides low dielectric constant for faster, more accurate signal transfer; Separate protective mylar foil and copper braid shield for rejection of RFI and EMI; Dual Solid Core center conductors for deep, tight bass response.
