@teo_audio you make some very interesting points and I especially like your dive into the concept of learning and hearing and learning to hear. I agree that in both fields people are able to advance. I know that since I have taken up this hobby my ability to hear has increased. I don't think this ability to learn in either fields will be equal for all however as there exist physical limitations among individuals. I have one ear canal that is of much smaller size than the other; is this difference going to hinder me over someone with nearly symetrical ears? The outward bend of one ear is different than the other therefore it won't gather sound exactly the same. The point being I think there are some who would be more 'golden ear' than others.

This vid goes quite a ways down the road to explaining why:
1) Power cords make a not so subtle difference.
2) Cable elevators should not be looked at askance.
