I woke up with cold ears

I've been doing a lot of critical listening, with a new amp (Luxman 507ux) and new DIY power cable. I've been trying to find an audible benefit or difference in either.


Regardless of my findings, I wanted to share something else, coincidental. I woke up, listened to music and it sounded horrible. Very tinny. Very bright. Gave up and decided to run the dishwasher instead... and guess what? The dishwasher too was too bright!

What I mean is, I was being irritated by the sound of it. To my ears that morning the dishwasher sounded like a chalk board.


What do I think I learned? That my ears are not consistent devices. That they too have their own sensitivities and behaviors which I need to take into account when listening.
