Actually just having your system turned on, or even the single component you are re-fusing left on (it is always a good idea change only one component fuse at a time until you determine correct fuse directionality) is sufficient in most cases to burn in a fuse, no music necessary. It is paramount however that you first determine correct fuse orientation on a fuse-by-fuse basis before placing in the next fuse in your system and again listening in both directions where the correct directionality should be readily appertains as more air and detail. If switching from a prior SR fuse model like Orange start Purple in the same direction, if it does not sound immediately better in most ways simply reverse the Purple fuse direction. Due to a new conditioning process, purple fuses may not always perfectly mirror the same orientation as prior SR Fuses. After determining the correct directionality for one or more fuses leave your system turned on to speed realization of best performance.
