The introduction in 1982 of the compact disc ushered in the age of digital audio. Audiophiles now have lots of new digital toys and technologies at their disposal, including SACD, DVD-Audio, MP3 players, hard-drive–based CD players, and digital equalization and room correction, to name a few. Videophiles have similarly benefited from digital technology, with an armamentarium that includes high-definition television, DVD-Video, Blu-ray, HD DVD (the latter two still on the horizon), DLP, LCoS, and D-ILA, among others. Action-based films have also benefited from breathtaking, digitally enhanced special effects. Even those of us who still prefer LPs must acknowledge—reluctantly, perhaps—the incredible impact that digital has had on our hobby (footnote 1).
It is a truism that audiophiles love music. What distinguishes us (footnote 1) from the vast majority of music lovers is the importance we ascribe to the high-quality reproduction of recorded music. But what, exactly, constitutes high-quality sound reproduction? To many audiophiles, the answer relates to accuracy. Useful indices of accuracy include many of the parameters that editor John Atkinson routinely measures: flat frequency response, time and phase accuracy, and low distortion, to name a few. On the other hand, many audiophiles apparently have little interest in these aspects and instead seek nothing more—or less—than a romantic and pleasant sound. Such individuals are unfazed by demonstrable inaccuracies in their systems; as long as it sounds good to their ears, they are happy. Are these two schools of thought both compatible with the notion of high-end audio? If so, is one "more correct" than the other? Are they mutually exclusive? What brought this issue to mind was, of all things, a digital transport. Actually, two transports.
