Not saying you're wrong or right but this is a weird conundrum with testing gear; some people claim to hear subtle differences and called out for it being placebo, but if some people can truly hear it and others can't then ultimately there's no way to tell if you can't hear it.

Placebo is also a thing. Even if there's no objective difference, if your brain says "this sounds better", then it does.

I really don't know what you hear but I can't fault you for hearing it.

Need more double blind tests because I suspect a lot of these testers would be destroyed and makes it harder to promote their affiliate links.
