Yeah, and the cool thing with the cambridge/creative volume controls is that they can even shut off the speakers totally.
I'm looking into a headphone amplifier/distributer, so that I can have 2 headphone jacks underneath the front panel... and using the creative speakers I can just kill them and plug in headphones - all without getting into the cab or adjusting software volume controls.
Since my cab is next to the living room like yours, I already figured out that this is a must-do, for me anyway.
