Warren: My thoughts on this are that most of this disc and specific track tend to "work" all of the components in the system to a much greater degree and do so in a much more consistent manner than any type of music does. Given that most music is a series of short duration impulses based on ( mostly ) standardized tuning arrangements, there are some parts of the audible spectrum that never really see much signal in terms of duration and / or intensity. In fact, there may be specific frequencies that are never reproduced as a primary signal in some systems. This is especially true if one listens to the same type of music using a limited number of instruments using standardized tuning in those recordings.
By slowly sweeping the entire spectrum using a steady state signal of longer duration, every part of the audible spectrum, and therefore the equipment trying to reproduce it, is given a thorough work-out. The fact that all of this energy is concentrated in a very narrow frequency region at a given level of intensity at a given time, and all frequencies are covered equally, is akin to working each muscle in your body individually, but in a very thorough yet equal manner. Most of the "work-outs" that your equipment undergoes during normal use does NOT do this. How this "conditions" or "demagnetizes" the equipment, i don't know. All i know is that it works.
When used in conjunction with the other tracks on this disc, it is the most effective method of "breaking in" componentry that i've found. Some of the other tracks maintain a very high average output level over a very wide spectrum, which is exactly the opposite of the narrow bandwidth sweeping of Tracks 1 & 7. The "equal but opposite" stressing of these types of signals on the gear is probably what is responsible for most of the benefits i notice, but i'm sure that there are other things going on here.
