Isotek won an award for this in 6 moons over 15 years ago ,I use it as a breakin cd as well as track 3 a 5 minute system demagnetized tune it it truly works I use it every few days if you go a week , listen to one track you know well. Then put on track 3 ,or whatever disc you own ,then replay the same song, it clearer performance and more settled. They stil sell the Isotek cd for $35 on line
I ripped it to my hard drive track 1 and 2 for large and small speaker run in
and works well with equipment taxing the capacitors for faster runin.
