Carlos, it is not the case that I am advocating the teleportation tweak or Magic Pebbles. I found a benefit from the teleportation tweak and with regards to the Magic Pebbles, initially heard nothing, then with a quite different placement found great benefit, and finally with the new H-Cat found I could no longer use them.
I know the effects of perceptual bias as well as the liabilities of DBTesting. I also know that it works many ways with people who don't want to hear anything less likely to hear one. But as I have said, I am seeking accurate and thrilling music reproduction, and will leave it up to those with more circuit knowledge to innovate. If I hear a demonstration of a tweak or component and it moves me toward greater realism, and if I can afford it, I will buy it.
My biggest problem with some on Audiogon is that they think they know all there is to science. Since there have been many scientific advancements since I got my degree in 1961 and when you got yours, I cannot understand why you would think what we know now is all there is to know. But even more importantly, if you don't try things that others find beneficial, how will you ever know that our understanding falls short. I encourage open-mindedness, as I know too often science gets into a set paradigm for years only to have some finding shake it up.
I don't teach any natural science, but science can be used effectively on social science issues and I teach the scientific method at both undergraduate and graduate levels. I was one of the very first political scientists to do so as I was advantaged by my science majors in undergraduate school.
Now that I am retired, I can venture to Houston more often. I hope to be down soon to hear Fred's Acapellas. You are invited to come up here also. I have no tube equipment now, however.
