I have done some searches and found much written about dealing with voltage variability but not much on consistent low voltage readings. I have tested the outlet I use for all my home theater gear and taken readings over several days and at several times. It consistently reads 115.3 volts to 115.5 volts. Other circuits in the house run in the 119-120 volt range. I know their is some tolerance in the gear for low voltage situations, but I wonder how much better performance I would get improving my voltage to 120 consistently. And if so, would it be more cost effective to have an electrician make repairs or just spring for a PS Audio or Monster AVS2000 that can correct the voltage deficiency? Any ideas?
