Timlub, glad to hear how you're doing! If anyone here could see my current setup they would laugh hilariously, it looks a mess... Speakers roughly 2 ft from back wall, about 6 ft apart.
What I learned to concentrate on, is eliminating all, and I mean ALL, unpleasant distortion from the system, and this can be very, very difficult to do. Everything matters, as they say, and if you don't fix everything then you are making it very hard to get it to happen for yourself.
How low should the distortion be? A simple test, when the system is working flat out on a "difficult", or any recording, is that a speaker completely disappears. That is, standing a foot away directly in front of one (left or right) speaker and in line with the tweeter (or high end reproducer) your ear/brain cannot pick that the sound is coming from the drivers. "Believe it or not ..." as I think someone once said ... :-)
Why this can happen is that the ear/brain compresses the loud sound, rather than the system. This is what happens naturally; how else can a player in an orchestra tolerate the sound level around him if this didn't happen ...
