Does your system sound better in the winter?

am i right? the voltage is down to 110.00 , Man give me that juice........shut off the ac.........Less juice, less quality?

I know their is a company called Exact Power that is supposed to deliver a constant voltage, but I dont understand how it can be done, if their is less juice in the neighborhood. I have a Tice PB, with a voltage meter and during the hot days it measures btwn 110 and 112 volts.
During the cooler days , its more like 118/119 volts.
The heat is a pain for me becuase Im trying to evaluate cables....and they all sound like crap!!
