The “NEW” Diamond Series XSR Speaker Cable. This is a special cable indeed. OFHC 6-NINES Beryllium Copper, Stranded, Laser-Prime Inducted Dual Conductor 10awg design makes for superior conductivity and a superior listening experience. Each conductor is Deep Cryo-Treated, then Electro-Harmonic Pulse Treated before and after final assembly. Capacitance and resistance are virtually the lowest in order. Low end transmission is fast and tight with no sub-sonic transmission loss. A Smooth, detailed, lush midrange and high frequency flow lends to a rich and vibrant tonality. Completely frequency correct, the cable has the ability to balance each frequency to the next making the Diamond Series virtually flawless in overall delivery. The Diamond Series represents a more "intimate" connection between amplifier and loudspeaker, creating a profoundly balanced sound, complete tonal accuracy with incredible detail and definition with zero sonic signature as well as being completely absent of grain, edge or “spectrum-blur” especially in vocals, overtones and instrument reproduction. Imaging with the Diamond Series XSR is as it should be, perfectly staged and represented with pinpoint accuracy. Inner program material becomes lifelike and extended in that the XSR allows more of the instrument and vocal “value” that was once hidden or “masked” to become present and audible without adding anything to the music that is not supposed to be there. Extremely transparent and open with the distinct ability to simply "dance" with any program material. Our opinion is the the Diamond Series XSR Reference Speaker cable is a new standard in how a speaker cable needs to perform regardless of cost or program material.
