The wattbox stuff is reliable in my experience. IP control is definitely a plus, especially for a network/comms rack. The AQ 707 seems more appropriate to power a ht rig as it has better noise filtration - but both are great lines of products ime.
My primary system is powered by Furman. The secondary system in the living room is powered by Panamax.
That being said, I encounter wattbox stuff at work all of the time and the pcs are great. I have seen 2 wattbox ups units fail, but I've seen far more go out than come back in.
