In a perfect world, all a serious record lover would need to enjoy music at home would be a single source component, one or two loudspeakers, and one good integrated amplifier. Speaker wire would be given by the dealer, free of charge, to any shopper who spent x number of dollars on new gear. Cable risers would come in cereal boxes.

Sad though they may be, Flat Earthers endure in getting two things right: In any music-playback system, the source is of primary importance; and in a music system in which LPs are the preferred medium, the pickup arm is of less importance than the motor unit—but of greater importance than just about everything else.

Woah.
