Products come and go. Some impress more than others, and in our little world, the ones that impress the most wind up in Class A of our semiannual "Recommended Components" feature.
After a product makes it to that list, if Stereophile's reviewers go more than a few years without hearing it againin a home system or a dealer's showroom or even at an audio showthat product falls off the list, usually quietly. Thus, if a reviewer is maximally knocked out by a piece of playback gear, yet the fates allow neither a purchase nor an extended loan, he or she or someone else on staff must endeavor to borrow it again so it can stay recommended.
