To me, at least, "snake oil" is a pejorative for tweaking. I can’t believe there is anyone posting here who hasn’t tweaked their components, their room, their overall layout. Some of us go to greater tweaking extremes than others. So what? How does it hurt someone if I share a tweak I’ve employed in my system that, to me, has improved the sonics of my system. You get to decide as the reader whether that tweak has credibility for you. I want to learn from others about tweak techniques that have improved their listening experience that I may have never considered!
I have benefitted a great deal from the experiences of others here and my listening experience is better for it. That and the great personal anecdotes that people share here are what make spending time here valuable to me.
