How many times have you put your new set of cans driven buy a nice amp on your Spouses ears , may be your GF, may be even your Daughter, only to hear them say, "that is nice". And you think "What the,..... "(you know what). Lets take a look at how we developed as a species. Way back before all the tech we enjoy today we depended on our senses in a much different way. If you were a Hunter, your sense of hearing was critical to your survival. The difference between becoming prey instead of predator, in many instances, might be ones ability to not only have good hearing, but the ability to differentiate sounds. The pitch of an animals growl, the sound of the under brush under movement, all can help identify the type of animal. Your chances of not only avoiding a predator, but acquiring prey required significant use of our stereo audio senses to locate sounds. Long story short, everything about your hearing, if your gender was the hunter, was designed to locate and differentiate sounds. You, through evolution, have been tuned to use your hearing in some very specific ways. Any experience that enhances these abilities is naturally welcomed by you. In other words, you are already set up to locate and identify sounds and your body craves any enhancement that may be available in this area. So,...when you are exposed to HeadFi equipment (Audio in general too) which allows you to locate and differentiate sounds better than you can normally do, you naturally like it.
Just thought about this today and it seemed to be logical. Anyway,...what do you think?
