Isotek Full System Enhancer & Rejuvenation Disc. This is for burn-in, full system demagnetization & rejuventation tracks.
I used it to burn-in a pair of new speakers during in-home audition period. Useful in my situation as the my in-home audition was shortened due to traveling.
It's now just sitting in a drawer unused so maybe someone else will need it. In very good condition. Light scuffs on the cover. Insert included.
$20 shipped in CONUS.
