The only changes that have been significantly noticable in my system are component changes, modifications to equipment (and sometimes those are iffy) and speaker cable /interconnect changes. I have yet to hear a footer make much, if any, difference, though I do use soft footers under every device (I've yet to uderstand how placing a component on a hard object such as brass or grantite can reduce vibration, though my feable mind can kind of understand how a soft footer could insulate from vibration.) Also, contrary to many here, I have yet to notice significant, if any, improvements from a power cord, though I have tried many hoping something will eventually floor me. I use tube dampers and various CD tweaks, but I'm not sure they make any difference.
The crazy thing is that although I doe not perceive that I can hear the changes from many tweaks, I keep using them, believing that if I take them out of my system it will somehow result in a degradation. On the other hand, I am very happy with my system as it currently stands. Perhaps the cumulative effects of the various tweaks I use do, somehow, make a difference. Or, perhaps I just want to believe.
