It can also be used by the advanced audiophile to set and maintain professional standards in a playback system. This record is unique in that it contains, on one disc, all the stereo and monaural tests normally needed during the working day. It includes standard reference levels and tests for frequency response, channel balance, turntable speed, flutter, wow, and rumble (signal/noise), tracking, translation loss, transient response, phasing, etc. Two bands of msic, superb examples of the recording art, provide a consistent, readily available source for aural comparisons and checks." And if none of that piques your interest, it's just a really cool record, for any Experimental-Noise fan!!! Blah >;]
