There's a number of good tracks on that disc. I burned the two demagnetizing tracks onto a CD one after the other repeating several times so they can easily be played and demagnetize during warmup. The effect is not huge, but definitely is there.
Other good tracks- walk around the room clavis resolving the room, when your system is dialed in it is uncanny how you can hear him walking around especially behind you. In phase/out of phase, when dialed in the out of phase is downright freaky, absolutely cannot tell where the sound is coming from!
This CD helped me learn to identify the differences between DACs and tubes and ss, by listening to the various music tracks and paying attention to their recording notes. Prior to doing this I noticed differences but never made the connection why.
Demagnetization was at first hard for me to hear. I would play these every once in a while, sort of thinking maybe better but never really sure. Problem is once you do it, you can go AB but there is no BA, you have to wait a while for things to go back.
What I wound up doing instead is run it every night no matter what. After a while this becomes your new standard. Once you get used to it, if you then don't use it a while then when the system goes back to grunge you notice! So now it is a regular thing, couple times a week, always before any long session I want to be real good.
