The very soul and essence of feeling stem's from those moments when I am at the keyboard. Those times when you put your soul into the music that you play.
I think this is, for me, what is at the source of my love for music. Many of us can certainly (obviously) appreciate music. I'm sure with training some of us could even recreate the notes. But, realistically, can any of us ourselves make MUSIC (speaking for myself the answer is a screaming NO!)? It's a rare talent to be able to pour that little something extra into the playing of the notes that makes it connect with people, that is able to convey the emotion, the feeling, and get through to people on a whole other level than just various vibrations on the eardrum.
I think that paradigm transfers to audio systems as well. Which for us is all part of the chase and part of what makes each system as personal as the music we enjoy and what we take out of it. You can listen to a great recording of a great artist on a boombox in an empty gymnasium. Does that do it for you? Probably about as much as listening to your kid's high school orchestra or swing band butcher some piece you love!
Some musicians, some systems are able to take you to another level. Most people I think don't give a shit. They'll listen to their Bose car radio with the sunroof open and Brittney or some other mindless radio blather droning on as background music and be happy as clams. Just like some people will happily drive to work and back every day in their Ford Festiva or Geo Metro. Even if they've tasted an M series BMW or Honda S2000 they remain unaffected by it and consider it a ridiculous luxury while people like us who have the "audio gene" could no more live the rest of our lives listening to assembly line music on assembly line gear than could the people with the "car gene" drive a Metro after having tasted something nearly sublime.
