The whole idea that different CD transports have different sonic characteristics when driving the same digital-to-analog converter is a vexing problem. It is easy to prove that even the cheapest CD players recover the data stored on most CDs with bit-for-bit accuracy, thus disproving the widespread and erroneous belief that errors in the digital code are commonplace and affect presentation aspects such as imaging, soundstage depth, textural liquidity, etc (footnote 1). If the datastream driving the digital converter is comprised of the same sequence of ones and zeros, regardless of the transport, what other factors could account for the sonic differences between CD drives reported by many listeners?

Audiophiles constantly seek ways to improve the experience of hearing reproduced music. Preamps are upgraded, digital processors are compared, turntables are tweaked, loudspeaker cables are auditioned, dealers are visited, and, yes, magazines are read—all in the quest to get just a little closer to the music.

High-end audio companies take different approaches to staying successful. One way to maintain a market position is to continue improving fundamental designs, offering a little higher sonic performance with each model. The latest products from a company employing this approach will look and operate very much like their first products.

The Krell KPS-20i (KPS stands for "Krell Playback System") is essentially a CD transport and digital processor in one chassis. What make the KPS-20i different from a CD player are the unit's five digital inputs, which allow the KPS-20i to function as a digital/analog converter for external digital sources.

Beginning with this issue, Stereophile readers will notice that more of the subjective equipment reviews are augmented with technical reports describing certain aspects of the component's measured performance. Although test data have lately been increasingly included in reviews, Stereophile has recently made a major commitment to providing readers with relevant measurements of products under review. We have just finished building an audio test laboratory featuring the Audio Precision System One, a sophisticated, computer-based audio test measurement system.

When I taught a recording engineering program at a California college, one of my first responsibilities to new students was to clarify for them what recording engineering was really about. Many of them entered the program with the impression that recording was nonstop glamor, with a significant part of the job devoted to partying with their favorite rock bands. It was my job to tell them the bad news: Recording was more about lying on your back underneath a recording console on a dirty studio floor with hot solder dripping on your face.
