"Analog's attraction lies in its ultra-high resolution capability, Spitz explains. Direct Stream Digital (DSD), the high-resolution digital disc format Sony used for its audiophile SACD format, is capable of 2.884,000 transitions per track per second, but a high-quality mastering tape contains approximately 80 million transitions per track second. "And that's just for 1/4-inch two-track tape running at 15 IPS," says Spitz. "The resolution goes up substantially with wider tracks and higher (tape) speeds."
