I have a suggestion about your confusion. Music is a universal language, and as such, it involves your subconscious more than your conscious mind. I would go with what you like more, rather than listening to a specific, such as a bass note, etc., because at the end of the day, you will like your music more if you go with that. In some cases, listing recordings and how they sound, can be misleading. I was just messing around with ASC tube traps, and the one in the middle between the speakers sounds better sitting closer to one speaker than another-so I go with that. It goes without saying that the power cords don't cross other wires, and(at least in my case) are lifted from the floor.
