Help My AC line voltage is 128V

Waiting for more inputs before calling ConEd on Wednesday. Who else has a measuring of 128V? Would a regenerator like PS Audio P600 or Monster Cable Voltage Stabilizer do some help? I have two 20 amp delicated lines and I want the purest possible so I don't want to add anything unless I have to... If the power from the delicated lines are clean enough I prefer not to add any stablizer / regenerator...

The choices are:
-----------------
CHOICE A
If the delicated line's power is clean enough, I prefer not to get a regenerator / stabillizer and will call ConEd to fix the problem.

CHOICE B
If the power fromt he delicated lines are not clean (let's say at least 90% clean?) I will then get a PS Audio P600, Monster Cable Volytage Stabilizer or an Exact Power EP-15... which steps down the voltage to 120V and cleans the power at the same time... If so, which unit above is the best? or do you have anything else to suggest?

ALL YOUR INPUTS ARE GREATLY APPRECIATED!
I WILL SHARE ALL RESULT LATER ON IN THIS FORUM FOR WHICHEVER WAY I GO WITH! THANKS!

I blew a few tubes on my Manley gear. Their engineers suggested voltage stabilization. I am using a Monster av2000 and a Hydra 8 for conditioning. I haven't had a problem yet and the sound is improved.

Extremely happy with my PS Audio regenerators. Have the PS600 for my integrated, PS500 for the digital front end.
Holds the voltage rock solid.

Thanks Michael, for the input. I am thinking about getting 2 P600s but space and sir circulations might not allow this. Are they HOT HOT?

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.
