Slv is pretty much right on the money. Nearly every, if not every, system will sound better during late night listening for at least the following reasons:
1. The system is probably getting more juice because most everything else in the house is shut down.
2. Less noise in the lines due to other appliances and motorized funtions and dimmers.
3. If your listening room has much sunlight coming it, the glare and/or brightness has a way of affecting your mood toward what you hear. Especially if it's bright behind the speakers.
4. Listening later at night, there are less noises in the house that can be disturbing and one generally is more relaxed anyway.
And every system should benefit sonically from proper line conditioning because all AC power has much noise and all digital will generate digital noise back into the lines and service panel thereby contaminating the other components.
The trick here of course is to stay away from poorly designed or mediocre line conditioners.
-IMO
