Line noise certainly is a noticeable difference dependent on the time of day and of course power consumption is lower at night as people go to sleep, other than those insomniac audiophiles.
I spoke to a electric company employee in my area and was informed the power grid starts ramping up voltages at about 2 in the afternoon and it reaches a peak at about 7-9 PM and then starts to slowly ramp down to about 12AM. It is interesting and of course may vary in different locales.
Also I would point out too that the solar wind moving past the earth generates positive ionic conditions on the sunny side and negative ions on the backside ( night side) of the planet. In experimenting with the negative tourmaline dryers and curlers, I am wondering if this ionic condition is also responsible for a little of the difference of what we hear.
