I didn’t mean that you can’t tell the difference between any two things if they aren’t side by side. Yes I do recognize, when I play music through my laptop speakers, the sound is not nearly as nice as through my nice floor speakers. But when I use $30 earbuds, I’m not particularly aware of what I’m missing by not using my $100 pair. If I compared them side by side, yes. It’s the same for a lot of things, like wine or whiskey.
