I don't doubt you hear it. I DO doubt you'd be able to tell in a dbt. Is that offensive?
I'm just stating what I'm observing. You
don't seem to understand much about it. There was a time not too long ago that I didn't either, and still don't entirely. I will say I
thought I understood it, until I really dug in and read up some more about it.
It's pretty mind blowing really, how easily your (or my) brain can be influenced by different input from our other senses. A lot of science is designing experiments to get away from cognitive biases because we know our brains can give false positives when influenced by other stimuli.
Sighted testing for audio is notoriously unreliable. I'm unaware of a single double blind test performed for something like this where the participants could do any better than chance at guessing which was which. Here is an example of one such experiment that demonstrates what I'm talking about.
Some of those participants were convinced they could easily detect the differences between a budget system and a high end system. Those differences disappeared when they tried it blind. I've never found an example that has shown otherwise, but if you can find one I'd be very interested to read about it.
FWIW I'm happy you're enjoying your new amp, it's a very good amp. This is a science based forum tho, and we're pretty big on evidence and testability. This forum's bread and butter is debunking audio myths. Your claims run counter to the evidence and general consensus around here so you should expect them to be challenged. You might want to read up on some of the work they do here...
