Speakers sound brighter at evening / night?

I don't know if anyone has noticed this or studied time of day and perception of sound. But for me, I've found in darker environment especially at night my speakers all sound brighter? A few other hypothesis:
1. Power is different at night 
2. My ear is different at night
3. Lighting is affecting perception of sound

"The study shows that we have brain cells that react to light when exposed directly. These results are encouraging, especially for bright-light therapy channeled via ear canal direct to brain tissue", summarized professor Seppo Saarela, PhD, head of  the biology department and leading the research at the University of Oulu.

Direct receptors of light? Yep.

Charles Ott proved that way back when - trouble was, psychology was even less of a science then, than it is now. I used to demonstrate some of his effects to students, just for devilment.

There is a difference between having the same type of skills as other people, just better or much better and claiming to have skills that are beyond our genetics and physical capabilities including the way our memory works.

It is like so called photographic memory which does not actually exist. People who claim that makes mistakes on recall and their memory is prone to suggestion just like anyone else. They do have better memory but not photographic.

You mean Dr. John Nash Ott and while he discovered links to human health and light spectrum he did not discover the light sensors in our eyes that regulate circadian rhythm nor extraocular light effects via the ear which does not appear to directly effect mood but has mechanisms, perhaps chemical based, that helps SAD and does generate a mild brain wave change.

Quite right. Memory failed on the first name. Ott may not have discovered the cells, but he identified numerous effects, which no-one took seriously for years and years.

Here's the thing. Why are you unable to make the same allowance? Why are you incapable of imagining anyone else being able to do something, simply because you cannot?
millercarbon, I know people can do things I can't do, and can hear things I can't hear. You may have better hearing than I do. You may be much less subject to perceptual shifts than I am. But that doesn't definitively explain what bwang29 is experiencing. I don't perceive speakers to sound brighter at night. Do you? If they really are producing brighter sound, then that should be easily measurable. If the brightness is really there but it's not measurable, then we have an interesting question of what exactly it means for the brightness to really be there vs it being a perceptual effect caused by the state of the listener's physiology.
