Originally named Disappointment for dashing Alexander Mackenzie’s hope that it would lead to the Pacific rather than the Arctic Ocean, the Mackenzie River is Canada’s largest, longest river system. Traversing 2,635 miles, it flows through a vast network of lakes, boreal forests and arctic tundra. Mackenzie’s many tributaries cover portions of three provinces—British Columbia, Alberta, and Saskatchewan—and two territories, Yukon and the Northwest Territories. Known as “The Amazon of the North,” Mackenzie’s sparsely populated basin remains one of the great unspoiled natural areas in the world.<br><br> Solid Perfect-Surface Copper+ (PSC+) Conductors<br><br> Perfect-Surface Copper+ has an astonishingly smooth and pure surface. Proprietary metal-processing technology protects the wire’s surface at every stage of drawing and fabrication. When high-purity low-oxide copper is kept as soft, pure and smooth as possible, it becomes a wonderfully low-distortion PSC+ conductor. PSC+ is manufactured by applying the same exceptional technology to an ultra-pure copper. The resulting sound quality is even more focused and simply less in the way. For over 30 years AudioQuest has pioneered the use of superior metals; yet even we were surprised by the huge leap in performance made possible with Perfect-Surface Technology. PSC+ simply outperforms all previously available copper metals at any price. All of Mackenzie’s conductors are solid. Electrical and magnetic interaction between strands in a conventional cable is the greatest source of distortion, often causing a somewhat dirty, harsh sound. Solid conductors are fundamental toward achieving Mackenzie’s very clean sound.
