Douglas- I agree with the greatest part of what you said. Everyone is born with certain innate talents and abilities. Many things are/can be learned, however, such as being able to listen to individual instruments or voices in an otherwise busy acoustic for instance. My hearing(and sense of smell) has saved my life more than once, because I learned to sense what did and didn't belong in the then present environment. That's how deer avoid getting killed too. They are very familiar with their surroundings. Deer that are around humans a lot, never learn to fear them(not good if you're a deer). If you listen to live music all the time, your recognition of it will adjust to whatever is going on with your hearing. If I were to stop listening to live performances, and lost some high freq. sensitivity: I would at that point have to boost the treble to get what my memory said was missing. If I stay current(and focused) in my listening: What I hear in the live venue is still what I am looking for from my system. I'm certain(though I have protected my hearing as a valuable asset over the years) that I have sustained some loss(still test very good), BUT- I've still no problem telling the silkiness of Zildgian cymbals as opposed to the brassiness of Sabians(for instance). The bands I run sound for keep calling me back, because they get compliments on their sound they don't get otherwise. As I said in an earlier post: It's a matter of what you love(That's what you will stay consistant with). I can't help the engineering or equipment used in the recordings I purchase. I do know that my system is accurate based on my reference materials, and if what's being played is lacking in some area: I know it's the software, and not my hardware. I fully agree with The Duke(and Mrtennis): If it sounds good (to you), it is good. I always say, "If one person likes it- It's art" (whether I think it stinks or not)!
