The System Enhancer is a compact disc that in just 74 minutes slashes the break-in time for a new audio system from days to a mere 6 hours. By sending a carefully controlled, mathematically designed signal through the system, the CD preconditions system components to work together smoothly and compatibly—removing the brittleness that a new system often imposes on the music being reproduced.
 
With Revision B, Purist Audio Design has improved the original System Enhancer by slicing break-in time to 6 hours and adding features that may improve the equipment’s sound quality. Used once a month, the System Enhancer continually reconditions a system to maintain peak performance. Each compact disc runs for 74 minutes and is made individually in real time—not pressed from a master copy like ordinary CDs. Using the System Enhancer couldn't be simpler: just drop the special disc into the CD player and push start.
