This article will answer this frequently asked question, “Is CD quality good enough?”

See the link for a year-long study done by the Boston Audio Society to test the audibility of longer word lengths and faster sample rates vs. standard CDs. It is published in this months’ Journal of the Audio Engineering Society

Spoiler Alert: Here is the conclusion: “The test results show that the CD-quality A/D/A loop was undetectable at normal-to-loud listening levels, by any of the subjects, on any of the playback systems.”

Well designed, controlled, and clever experiment, again debunking those afflicted with aural hallucinations.
