When I worked in a hotel in Flagstaff, I was walking in a tile passageway with the head of housekeeping. She said that there was something that smelled bad. My sense of smell is pretty good. There is nothing wrong with it. I took a deep inhale through my nose. Nothing. It smelled fine. She insisted looked around and then looked way behind a vending machine in the corner and was a wrapper that had some old rotting food in it.
Some people's senses are just more sensitive than others.
Thank you very much. Even though you are unaware, you just posted full support of "EE types" vs belief. What you posted was a demonstration of actual sensory ability, using semi-controlled single blind methodology. "Blind" means "not knowing", not "blindfolded". Neither of you knew or could obviously see priori exactly what the source was. The non-audiophile used her senses to home in
using that sense, smell, to locate the source.
That is exactly what "EE types" advocate based on 200+ years of scientific knowledge.
The audiophile method would have been to make sure they were told and knew about priori/saw the food at all times, during their 3 month "long term smelling" "test".

Yes, a perfect example of "trust your nose", "nose only", "just smelling" test. Thanks, even if inadvertent.

Btw, this thread is actually about a demo where the level
measurably increased 2-2.5db.
There is no dispute differences were heard with the cable swap. FYI.
cheers,
