Wow, OP has to be totally confused after all this! Unfortunately, optimizing audio systems is very complex undertaking, lots of good advice through thread. Only personal experience with advice here will get you to system's full potential. Changes you undertake will have variable results.
In the end, every single thing in your system, from the ac feed to room has an effect on sound stage and imaging.
I don't know if this has been mentioned, but many rooms are not symmetrical. Positioning of speakers and acoustic treatments must take this into effect.
