All very good points. We do all have the same biological makeup, and there is no question about psychological biases. No question they do influence judgements, opinions, preconceptions, etc. "Bose makes superior sounding speakers." Try posting that on the AVS board.
Isn't it also amazing what sounds/noise/music and the effects they can have on human beings? The pleasure that music can give. Another the crying of an infant causing discomfort in human adults. The adrenaline rush caused by a thunderclap very close to you. All very interesting things and the effects it has on people.
All in all, it's a wonderful world that has been opened to me while getting into great audio. Just glad there are some very good people here to help me experience and enjoy the ride.
