Mine also sounds better at night. At night people are in bed sleeping so you have fewer electricity poluting things on line. I found that as I go around turning things off for the night my system gets quieter.
Your neighbors polute your electricity. Things like fluorescent lights, TVs, dimmer swithches. These things and many more put garbage in the electrical system which shows up in the background of your system.
