Really? I haven't seen it. Although I'm a devout non-believer in tweaks, cables, power cords, supports, green pens, oak feet, wooden knobs, silver goops, Shakti stones, etc., etc., etc., I have always been happy for the believers to believe in them. We all hear and perceive things differently, so if you heard a difference, as far as I'm concerned, you heard a difference, and it doesn't matter whether that difference existed only in your head or in measurable physical reality.

Like smell, sound does not exist outside our heads, it is the reaction of the ear-brain system to certain compressions and rarefactions in the atmosphere, and it is subject to that system, including psychological/expectation/whatever factors. I only ask that a statement such as "power cords make a difference" not be presented as a law of the universe, as is sometimes the case, but as an individual perception. To the best of my knowledge, all the objectivists I've observed on this forum work to these same principles, and I think that talk of an "objectivist take-over" of ZeroGain is much exaggerated.
