"Dear Don, Got the Model 570 Speaker Cables yesterday and hooked them this morning. Wow. Much nicer than described. Highs are better defined, mids unchanged, and bass licks rock solid (esp tom-tom, bass drum, and bass guitar). Very MUSICAL indeed. No ear fatigue. Bonnie Raitt, Sting, and Carlos Santana never sounded better. Thanks," Bob B. Paducah, KY.
More about Continuous Cast Silver & Copper.
The most important factor in cable design is the quality of the conductor. The introduction of Continuous Cast Silver & Copper allows the creation of virtually perfect conductors. A heated mold forms conductors of nearly perfect structure, with flawless, mirror-like surfaces, and high flexibility and great fatigue and corrosion resistance.
The grain (crystal) structure of metals has always been a limiting factor in cable design. Gases and solid impurities collect at the grain boundaries, forming non-linear (diode) junctions. These non-linearities cause the harsh, grainy sound quality of many cables.
A one-meter strand of drawn silver or copper wire, 0.3mm in diameter, consists of from 50 to 40,000 individual crystals (depending on the quality of the silver or copper). Since no conductor is absolutely pure, each crystal boundary becomes a diode, adding its own non-linearity (however weak) to the signal.
The Continuous Casting process eliminates this source of distortion by eliminating the grain boundaries. In Continuous Cast cables, each crystal is 125 meters long. This means that, even in long cables, there's never more than one crystal junction per strand.
The single-crystal structure permits unimpeded signal propagation. The result is an extremely neutral sound with grain-free, extended highs that are open, airy, and detailed. This improvement is apparent throughout the full frequency range, even down to the bottom end, whose weight, space, and air are fully reproduced.
