[Vreek Fonq]

And what is this?

 

[BeeKay]

Either an electrical problem or simply some dirt?

Good eye!

Dirt probably but could be worse if it's solder residual.

Being a photographer by trade, taking by the amount of reflection and highlight crush, I suspect it to be metallic in substance.

You made me read it one more time and I stillI don’t see any mention of the OS mode that was active at the time measurements were taken. What am I missing?

From the review:

With default filter, there is still some out of band noise to reduce performance but impact is low:

Go to "non-oversampling" mode and ultrasonic noise shoots through the noise, causing that off-the-charts green line. Best not to have a tweeter that attempts to go above 20 kHz!

That’s not what Golden Sound is complaining about.

You do have a really good eye!
I am trying to have my best shot with my old Canon 6D&100macro, that is a metallic.
