I guess my hangup is that knowing what the products are that you're listening to doesn't always lead to you liking the sound of the higher-end component. I'm wondering how the mind decides which one it prefers in those cases. Is it simply the more inconsistent methodology making the results more erratic?
The problem is that when you know the product(s) being used and if you already have a preconcieved notion of one of the said products, then you will be relating/comparing all tests back to that one (or more) item(s) you already know, creating a biased test either in favor or not in favor of the known product.
