Best Power Conditioner?

I know its not on your list, but the Equitech "Q" series balanced power conditioners are what I feel are the best. They have very powerful units that are still shelve "mountable". They even have in-wall units powerful enough to run your entire home's electrical system. The PS Audio regenerators sound very nice, but they are too inefficient to be pratical. You cannot run power amps from them at anything but very low volume levels. If you have subs, a plasma or other high current requiring devices, forget it.
