Volleyguy,
Every progression you have made over the course of this thread your choice of caps your choice of inductors your exposure to different wires all have a common link...resonance control. I may have missed your comments on the application of resonance control to the largest radiator in your playback system...the speaker cabinet. Unless properly grounded and terminated vibrational fundamentals and their near endless harmonics are radiated from the cabinet along with the intended music originals from the drivers themselves. Like your horns vibration can be give direction and focus. As in other components you have now adopted and admire, resonance collection and mechanical grounding are key to musical performance.
