Golden-eared audiophiles have long testified to vinyl's warmer, richer sound. And now demand for vinyl is on the rise. Pressing plants that were already at capacity are staying there, while others are cranking out more records than they did last year in order to keep pace with demand.

Turntables are hot again as well. Insound, an online music retailer that recently began selling USB turntables alongside vinyl, can't keep them in stock, according to the company's director, Patrick McNamara.

And on Oct. 17, Amazon.com launched a vinyl-only section stocked with a growing collection of titles and several models of record players.

Big labels still aren't buying the vinyl comeback, but it wouldn't be the first time the industry failed to identify a new trend in the music biz.

But when it comes to vinyl, these organizations don't really know what they're talking about. The RIAA's numbers are misleading because its member labels are only now beginning to react to the growing demand for vinyl. As for SoundScan, its numbers don't include many of the small indie and dance shops where records are sold. More importantly, neither organization tracks used records sold at stores or on eBay -- arguably the central clearinghouse for vinyl worldwide.

Vinyl's popularity has been underreported before.

"The Consumer Electronics Association said that only 100,000 turntables were sold in 2004. Numark alone sold more than that to pro DJs that year," said Chris Roman, product manager for Numark.

And the vinyl-MP3 tag team might just hasten the long-predicted death of the CD.

San Francisco indie band The Society of Rockets, for example, plans to release its next album strictly on vinyl and as MP3 files.
