As an audio scribe, the fiercest demons I wrestle are beliefs—yours and mine; those of my friends, my editors, my fellow reviewers; and those of the engineers and promoters of the products I write about. Sometimes the force of these rabidly held and (mostly) conflicting beliefs paralyzes me with self-doubt: What do I know? What makes me qualified to listen and judge?

Most new preamplifier-processors now fall into one of two categories. First are the fully featured models, with ever-growing numbers of channels to support such immersive surround-sound formats as Dolby Atmos, Aureo3D, and DTS-X. An example is Marantz's 13.2-channel AV-8802, which replaces the 11.2-channel AV-8801—a sample of which I've owned for barely a year and use only in 5.2! The second category is that of such high-end models as Classé's Sigma and NAD's M17, which offer only 7.1 or 7.2 channels, and from which nonessential features have been trimmed in favor of audiophile-grade circuit components and construction. But if money is no object, there is a third class of pre-pro, exemplified by Trinnov's Altitude³² and Datasat's RS20i, in which no compromise is made in any of these parameters.

Before hitting the Refresh key on last month's column, which was dedicated to the challenges one encounters when evaluating audio cables and other accessories, I'd like to share with you a true story: a cautionary tale, as it were, about the hazards of writing reviews for a living.

Seven or eight years ago, just as spring was returning to upstate New York, I made my annual trek to Montreal for Salon Son et Image: one of my favorite audio shows for a number of reasons, not the least being the fact that I can travel there by train.

The Sheffield Drum Record
Improvisations by Jim Keltner and Ron Tutt (drums)
Sheffield LAB-14 (LP) (1981). Reissued as FIM DXD 001 (CD) (2010). Bill Schnee, Doug Sax, prods.; Lincoln Mayorga, exec. prod.; Steve Haselton, Bill Schnee, engs. TT: 13:49.

There was a time when drum records were as common as records of steam locomotives and thunderstorms. It has been so long since anyone has tackled any of them that a lot of technology has gone over the dam, but they are precisely the kind of program material which illuminate the state of the audio art like nothing else. Thus, Sheffield's Drum Record emerges as a landmark—a technological tour de force that should discourage anyone else from issuing a similar disc until the state of the art advances by a few more years.
