Better sound at night?

[BoyScout]

Now it's an excellent time of the year to reconnect to this subject. One could listen to music when it's dark outside in the afternoon (at least in north Europe) and compare with the late evening. Do you notice any differences?

I´ve nothing to compare:
Different house, different room, no Devialet (in transit from Paris with the CI)...
So, everything will restart from the beginning.
