The SoundStage is 'visually' a great tool, but I couldn't get it adjusted right - it always makes it sound very in the high range.
Do not be afraid to REALLY adjust the EQ response with that plugin. Also, remember that EACH "player" in the Soundstage space has its own unique EQ, damping, and all other settings.
Finally, SoundStage is not a strong generator of reverb "tails." I would generate tails with a single master reverb, and use SoundStage exactly as its name implies--to place players on the stage. And don't forget that you want to use several instances of Soundstage for best effect. One great technique I've discovered with SoundStage is to define four overlapping stereo images in a semicircle around the virtual "podium," and another ring of four images as a "backline." This gives you a total of eight potential bussing destinations for each stereo track. The best way to set this up is to define a single preset for ALL the players and the mic position, then activate the desired players as you open the multiple instances. You DO want to try keeping the basic reverb elements the same, so that the mics stay in exactly the same place--only the players move. If the mics move, the "trick" gets blown.
