"But it sounds better at night...."


A well-traveled topic that I raise yet again.  On the "are power regenerators snake oil" question, the response that has made most sense to me is: No, if you have some material issue with the power supply coming into your home.  If you live in an area with what I will call normal modern power infrastructure, and have quality components, you will probably not notice a difference.

But I live in a city, do not suspect any power problems, and feel with a pretty high degree of certainty that my system sounds better at night.  This is a common sentiment, attributed to more activity on the electrical grid during the day.  Can these two positions be reconciled?  Why DOES the system sound better at night to me and many others?


Is our perception straight-up wrong, and the result of some bias or non-auditory reason why listening at night is a better experience?

Maybe when listening at night, one average for most people, the system will have been on longer, and therefore be more warmed up?

Is our perception real, and supports the proposition that baseline electrical system usage does materially affect many systems, and you don't need a clear power "problem" to benefit from a regenerator? 

Let's rehash it all again gentlemen!

I believe it is partly because there is less interference on the mains at night. Fewer industrial motors drawing power and causing mains feedback. But mostly it's a psychoacoustic effect caused by the lighting in your room. You eye is drawn to the brighter area and it takes your mind off the music and can even make you think the balance is off. A dark room eliminates the optical distractions and allows your brain to focus on the music. I have the ability to block out all the light in the front of my audio room with a small amount of light allowed at the rear of the room behind the main listening position I believe this light control creates the illusion that the room sounds better this way Just my opinion.

Definitely sounds better at night because most of us don't "drink" during the day!
