Audio or video component recommended by Stereophile magazine or the Stereophile Guide to Home Theater as having exceptional quality with components receiving a grade from A to F (A being one of the best money can buy in the category and F being a good quality component superior to many others but having limitations in absolute terms). Stereophile is a highly regarded industry publication. While buying decisions should be based on personal opinions and ideas, the Stereophile Recommended Components provide a good place to start. It should be noted that not all equipment is reviewed by Stereophile and so the list of components is not based on all equipment available but just those reviewed. Also, most recommended components, particularly those in the A and B range, tend to be expensive.
