I am using Spica TC-50s in my bedroom, and couldn't be happier. They excel at sounding great at low volume; on the other hand, they don't get very loud. As you crank the volume knob past a certain point, they stubbornly refuse to get any louder. If by whole stage, you mean full frequency range, you might want a sub with the Spicas. I have mine paired with a JJ828 integrated and Sony XA777ES. The JJ is great for (among other reasons) having a remote control power switch, so you can shut it off without getting up.
