Components listed here have been formally reviewed in Stereophile and have been found to be among the best available in each of four or five quality classes. Whether a component is listed in Class A or Class E, we highly recommend its purchase.

Each listing—in alphabetical order within classes—is followed by a brief description of the product's sonic characteristics and a code indicating the Stereophile Volume and Issue in which that product's report appeared. Thus the May 2015 issue is indicated as "Vol.38 No.5."

It's one of audiophiledom's eternal questions: What can we do to draw more music lovers into the audiophile fold?

Of the proposals bandied about on audio forums, two seem predominant: a) sell stuff more people can afford, and b) sit your neighbor or the cable guy in front of your stereo, cross your fingers, and let 'er rip—the theory behind b) being that the experience will be so epic as to transform the reluctant participant into an audiophile butterfly. As if.
