I have! I really have! My friend spends all his money on audio. I sadly just don't understand. You are correct. I was going to say that he pays infinite money for what to me is a 10% increase in enjoyment, but perhaps for you and him, your brain is better with sound, and you guys might get a 1000% improvement for your dollar.

A 200$ pickup is certainly better than a 20$ needle, maybe even 10x better The difference between a 200$ pickup and one that goes for 2000$ is miniscule. There certainly is a difference, but it's never as big as between the 20$ and the 200$ model.
That said, there are listeners who believe in the value of a 2000$ pickup and derive a lot of enjoyment from the difference to a lesser model. Who am I to say they're wrong?
