KEF's Home THX speaker system is somewhat unusual in that it includes an active subwoofer. (While most Home Theater subs are powered types; it's just that few THX models are.) Although powered speakers have never enjoyed much popularity with American audiophiles, they can yield better results than the mix'n'match approach because each amplifier/driver combination can be optimized.

At the 133rd Audio Engineering Society (AES) Convention at San Francisco's Moscone Convention Center, a full house flocked to aptly numbered Room 133 on October 27 to hear Stereophile's John Atkinson and four other major audio professionals deliver a two-hour presentation, Loudness Wars: The Wrong Drug? Sharing the stage were the panel's chair, Thomas Lund of TC Electronic A/S from Risskov, Denmark; Florian Camerer of ORF of Vienna, Austria; fabled recording and mastering engineer Bob Katz of Digital Domain in Orlando, Florida; and the equally fabled George Massenburg, McGill University, Montreal, Quebec, Canada, who engineered, among other things, that audiophile favorite, Jennifer Warnes' "Bird on a Wire."

In such an environment, line-level sources (eg, DAT, CD, even analog tape) deserve special attention.
