As I mentioned above, this type of device seems to take a week to settle in after interrupting the power to it. Thus, an on/off switch really won't make for a valid A/B comparison, in my opinion. It seems odd that Dave chose to put such a switch on this device; there is no such switch on the UberBUSS. Why not just pull the plug out of either the back of the unit (assuming the cord is not captured) or the wall outlet?
My Z-1 also has a switch and a very short (18 inches?) captured cord. In its case the switch adjusts the level of power factor correction applied and you can hear the difference through A/Bing that switch while the unit stays plugged in and thus powered up. The labeled "A" position is almost always the best sounding setting for it, I've found.
