All that does is stifle progress.

Marco.
On the contrary I'd say that jumping to the wrong conclusions about cause and effect is the worst possible thing for progress. If you don't know how it works then you can't improve on it, except by chance.

There's plenty of times that a difference is pretty obvious and there's no question that the sound has changed. Then there's those occasions where we think we hear a subtle change. It's only in those latter situations that we have to question what we think we hear. Especially if there is no credible reason for there being any change.

We have to acknowledge that we can be fooled by our senses because it is a fact that we can be.

To me that is the practical and realistic approach. Imagination Land is not a good place to be putting a hi-fi system together or doing anything else, for that matter.
