Gbmcleod, the magic of great realism in sound production is quite fragile as you suggest. However, it includes many things you don't mention such as the speakers, your position, whether the power cords are on the floor, whether the speaker wires and ics are close to power cords, etc. And there are limitations, of course, such as what others think of the system you have laid out. My wife said, "I'm tired of having a sound laboratory in my great room."
Presently, I am working with the room treatments which are so critical in my very small listening room in New Mexico. It is 10x13x8 feet. I found that one of my Zilplex resonators was one eighth of a inch lower than that on the other side and was moving the sound stage toward the other side. These things are very powerful although they are just one half inch in diameter silver bowls.
I should also say that seldom having the isolation devices in each of the four corners of a component is the best location for them. If you have great latitude for placement, put one under the main transformer. Trial and error is the only game in town.
