Today's turntables are a pricier, however, than they used to be. A can run as much as $6,200. Even run as high as $150,000.

Audiophiles who haven't listened to an LP lately will likely find that the quality of sound on today's albums surpasses that of the old-school vinyl of the 20th century, according to Bizar and others.

In the 1980s, companies pressed vinyl into records weighing 120 grams. Today, records are thicker, weighing in at 180 grams -- and they're recorded with more sophisticated electronic equipment, Bizar said.
