We all know that a stable and constant voltage feeding into your audio component always reap better results that a fluctuating incoming voltage. And none will do it as good as the Monster AVS-2000 at this price. For under $500, this is a lot of hardware for the money. Heavy duty transformer, solid steel case all around and 6 outlets distinguishes it from the rest of the pack. We have the original box for it (a bit run down). There are some minor scuff marks here and there but otherwise, the unit is a solid 8/10 and works 100%.
