Some say it dates back 50 years, to when the late David Hafler introduced a tube amplifier with a "better-sounding" ultralinear output stage. Others claim it goes back to the introduction of electrical recording and playback in 1927, when <I>Gramophone</I> magazine's founder and editor, author Sir Compton McKenzie, thundered that electrical reproduction was a step <I>backward</I> in sound quality. But whenever it started, the "Great Debate" between "subjectivists," who hear differences between audio components, and "objectivists," who tend to ascribe such differences to the listeners' over-heated imaginations, rages just as strongly in the 21st century as it did in the 20th.

Medford, Long Island&ndash;based manufacturer Shahinian Acoustics has announced a recapitalization and a manufacturing-facilities expansion to meet demand for its quasi-omnidirectional loudspeakers.

Can the power cord make or break a particular component? Some say it does and others say it doesn't. Have you upgraded the power cords on any of your equipment?

Like the Reference Studio/60, which was <A HREF="http://www.stereophile.com/loudspeakerreviews/1204paradigm">enthusiasti… reviewed</A> in the December 2004 issue by Kalman Rubinson, Paradigm's floorstanding Reference Studio/100 is now available in a v.3 version. The '100 is the flagship model in the Canadian manufacturer's Reference line. Its earlier incarnations, the original Studio/100 and the <A HREF="http://www.stereophile.com/loudspeakerreviews/252/">Studio/100 v.2</A>, were reviewed by Tom Norton and Robert Deutsch in the August 1997 and June 2000 issues of <I>Stereophile</I>, respectively, and both writers were well impressed at how much sound quality could be wrought from this competitively priced speaker design. Bob Deutsch, in particular, referred to the v.2 as a "a serious high-end contender, and a formidable one for just about any speaker in its price range and even well above."

Experienced reviewers know that shows are the wrong environments for critical audiophile listening. Convention centers&mdash;especially the one at Las Vegas&mdash;are huge, cavernous airplane hangers, not the intimate listening rooms reviewers thrive in. Extraneous sounds from subwoofer blasts and the constantly milling crowds leak in to sully the music. Booths set up by manufacturers on the show floor have very thin, flexible walls, and no bass treatment.

Media conglomerates have long hedged their bets by consulting demographics experts and marketing gurus. Now, music executives have real science to bolster their sometimes unreliable instincts about what will succeed and what will fail. It's an audio analysis program called Hit Song Science (HSS).

Xd on its way: <A HREF="http://www.nht-hifi.com">NHT</A&gt; has begun shipping its Xd DEQX Calibrated DSP speaker systems to dealers, according to an announcement made January 24 by parent company the Rockford Home Group.
