bigtwin, I can understand what you have experienced but I think you (and others perhaps) may be missing the point about bringing the speakers out into the room. I'm using a equilateral set up with speakers about 9ft apart and 6ft from the wall behind them. I too have never been able to bring the front of the soundstage out into the room. It is always on the rear wall, BUT the difference as I experience it with most recordings is that the image begins at the rear wall and extends much further behind it. With the speakers closer to the wall this depth disappears substantially with the concurrent loss of resolution.
And, as I said earlier if you want to hear what your system is really doing, soundstage wise, you need a recording in which the information is embedded. I referred to the Opus 3 recording called 'depth of image' for the obvious reason, but also because the recording is accompanied by the producers description of what you should hear from each cut on the disc. I've heard this recording on a great system and can tell you that it is all there. I've used this recording a a gold standard for setting up my system. I hate to admit this, but while I have worked hard for many years I've never fully achieved it fully. But hearing it initially, over a modest High End system properly set up, was an unforgettable revelation. FWIW
