Just to add my 2 cents. I re-arranged my system yesterday with thoughts of why am I bothering to do this now? Is it worth the hassle? Can I set the speakers back on the same markers with the right toe in and angle? Even if it sounds good, will my wife like the new setup?
Well, I must tell you that glorious music abound as a result of all this painstaking, rearranging, backbracking(furniture)sweat.
Soundstage depth and height are now floor to ceiling (literally) and the sweatspot is wider and taller than I thought it would be.
Night and day is the difference. I am totally shocked at the dramatic change.
As for the key reasons why? Well, it has to do with the new ICs I installed, and most of the credit has to go to the Audio Horizons preamp. But above all, the Room plays a key part in freeing up my speakers to do their special disappearing act.
