That's the problem. You're using your brain to measure things. Human brains are prone to bias and mistakes, because you want to justify your purchase decision. Again, we're not arguing that you think they could sound different. They certainly could, but it doesn't mean the one 100 bucks more expensive is "better". If there is a difference then there's distortion. You certainly could like one more than the other, doesn't mean the one you like is objectively better.

Don't talk about being smart when you're using completely subjective methods to support your argument.
