Making digital audio sound good appears to be a much more difficult job than its developers first realized. When digital audio was in its infancy, there was a tendency to think that digital either worked perfectly, or didn't work at all. This belief led the engineering community to devise ill-considered and flawed standards that affect the musical quality of digitally reproduced music today.

Editor's Note: Published in 1998, this was the final review written by Stereophile's founder, the late J. Gordon Holt in the 37 years he was associated with the magazine. In it he expounds on his passion for experiencing recorded music in surround sound. Our continuing focus on two-channel products and recordings was one of the reasons Gordon eventually resigned, in August 1999.—John Atkinson

Our first sample of this preamplifier was returned to the manufacturer before we had completed our tests on it, and was replaced with the latest version (ours is serial number 500108). Enough time elapsed between the time we shipped back the first sample and the time we got around to auditioning the second that we are unable to report on any sonic differences between the two.
