Help My AC line voltage is 128V


I have recently tested the line voltage reading out from my AC lines. They read 128V ! Knowing that 128V is almost 10% more than the standard 117V and most components inside the equipments have a 5% tolerance only. Would this unusual high voltage damage my equipments? Even though I have all my stuffs hooked onto a delicated line but when my wife uses the washing machine, the power reading jump slight up and down... This is a power spike at a high 128V... Sounds dangerous to me... I now have a habit of unplugging them everytime I finished and I am getting frustrated at this. Will getting a voltage stabilizer help? PS Audio P600 or the Monster Cable stuff?

My P600 powers a 200 watt per channel amp along with two REL Storm III subs and I am known to shake the walls ocassionaly. Medium warm, I would say. Nothing like a Class A amp temperature that's for sure.
I see... These monster are huge, they are like an 500W monoblock... Now I got the temperature problem put aside, I have to consider getting a new rack with a higher clearance (for the bottom shelves) just for them two. I will keep you guys updated with the result for using the P600. Heard about the Exact Power stuffs and Balanced Power stuffs, they pack the same feature (voltage stabilizing + conditioning) in such a smaller box, are they anthing good when compared to P600?
I had the power plant for 2 weeks and didn't care for the sound. I believe you can still get a 30 day trial period so you can check for yourself. I do like the idea of the Monster displaying the constant changes in the voltage. I sometimes have immediate swings of 7 volts! I plug all components into the Hydra8 and then plug the hydra into the monster avs2000. A big and open soundstage is the benefits.
