First: Good on you John, so few have spent any time on core material properties. I have developed a method for passive self demagnetization in E/I core. Works a charm except that higher perm materials become harder to drive and the driver circuit begins to distort. High voltage lateral Fets appear to mitigate this. Main reason for using E/I core is that except for rise time limits across the FR band the core is done by 500Hz, even in 9mil M3. This means I am free to treat the coupling speed as modified by surface depth and dielectric constants involved in the coil, to tailor it to the core "speed". Works a charm in guitar amps and provides massive amounts of information for audio reproduction.

Second: This electricity quality quandary appears to me to be related to electron population in the power grid. Based upon the theory that AC signal is only involved with electrons when there is a vector change and otherwise ignores them. You can experiment with this in your own systems by taking a 2 foot length of lamp cord, splitting it into two lengths, stripping the insulation back 2 inches on both ends of one piece and making a loop by, connecting both ends together. You have in this a very low impedance wave guide, for information to ring in, that would ordinarily go to ground at the power station until it is pulled back through to form the back half of the wave form. The reason for doing this is to provide a convenient place for electrons to "cloud" and seethe within. The heavy population of electrons in this loop will aid in maintaining the information structures of your audio. Apply it to the ground connection for your amplifier, not the negative of the live power connection. Maintaing the information content from the back half of every waveform blasting through your system is the key to a more "natural" sound. A dearth of electrons on the ground in your power grid will cause your audio to become thin in character, your illusion of 3D space presentation to collapse and a general discomfort in your mind.

Three: Now finish the other loop and try these same loops on your speakers, connected to only the return side or black colored connector. You should get some interesting results. Not necessarily better results, but, any difference, after a few minutes time, does indicate that a bit more sophisticated investigation would be worth your time. I would then suggest you investigate "Ground Control".
