Anyone who knows about music fundamentals, are aware of the 4 important characteristics necessary for the accurate reproduction of music reproduction, and it’s sounds. These 4 specific qualities are, in no particular order : ( 1 ) Dynamics; ( 2 ) Pitch; ( 3 ) Tone color; and ( 4 ) Duration. Whether in a home environment, an audio system, or actual, playing musicians, or a live venue ( non amplified ), it is wonderful to experience all 4, in order for me, at least, to appreciate the performance. Of course, over time, words such as imaging, sound staging (depth, height, width ), localization, prat, you get the idea, have all been terms created by audiophiles, such as Harry Pearson, and others. I am not questioning the importance of Eric’s initial post, but, with our ear / brain ability to pick up on the direction and orientation of sounds ( and yes, noises, all pressurized vibrations we pick up with our ears ), gives us the ability to hear all of what has been discussed here in this conversation, and so many other conversations. As we are all different and individual from one another, as we all listen and hear differently, as we all have our own " perceptions " as to what is important, and / or real, as we all have different experiences and backgrounds, I have to agree with goeffkait, as to " what is the difference ". We are all correct, as long as we continue on our journey, and can find happiness and enjoyment, with whatever music listening endeavors we experience. Enjoy ! MrD.
