Working alongside Steve Silberman of AudioQuest, Wavelength Audio’s Gordon Rankin offered a series of talks on computer audio for Mac users, while Jim Hillegass, the founder and CEO of JRiver Inc., offered corresponding seminars for users of Windows-based computers. My schedule allowed me to hear only a brief portion of Gordon Rankin’s Saturday seminar—and, regrettably, none of Jim Hillegass’s talks—yet even so, I learned things I’d never come close to knowing before. (An exemplary gem: When it comes to RFI rejection, Apple’s laptop computers are considerably better made than the company’s desktop models.)
