My soundstage increased to where I wanted it upon the following:
Upgraded to an incredibly good preamp (Jeff Rowland Criterion); upgraded speaker cables to the best I could afford. That gave me the depth and then the cables shaped the rear of the soundstage and gave it the definition. I then added 6 Hemoltz Resonators (Vicoustic Bass Traps) and that took out any bass smudge that was taking away from the definition of the depth of the sound stage. I then upgraded my turntable, arm and phone stage and it just spotlighted all of the information from front to back with gobs of music.
