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.

The only thing that will change "brightness" of a speaker at night would be a change in relative humidity coupled with a bigger room and moreso with limited absorption.


A poorly designed amp sensitive to AC voltage but seems unlikely.

More likely it is a day that thas desensitized you to low frequencies.
