Here we go again. Geez, so now you're going tell me that only conductive devices in the signal path can be defined as real audio tweaks? Have you by any chance been living in a cave in Borneo for the last twenty years? By your "logic" all the mossback tweakaphobe scamps out there would dismiss out of hand tiny bowl resonators, any kind of resonator, SteinMusic Harmonizer and Magic Stone, Shakti Stone, Mpingo discs, anything with the word Quantum in the name, electron microscope stands, things that are just too damn small to do anything (like fuses), anything with the word Magic in the name, Schumann frequency generators, anything even remotely involving crystals, anything not in the signal path, anything you can't DIY with something from Home Depot or sand and things you can't find out all about on Wikipedia or Electronics 101.
