> This is my favourite BS argument by audiophiles when defending some impossible claim or other: you have to listen to it.
Just like a lot of engineers will tell you, that having studied a topic on university/college doesn't make up for "field experience".
> Then the next step is always some disparaging remark that you can't hear the difference because your system isn't "high enough resolution".
It's true. Just like there is differences in quality of measuring instruments (cheap china multimeter vs. Agilent or the like) there is difference in electronic components for audio reproduction.
I have one other disparaging remark for you: Not only is your system not resolving enough, your ears are not trained enough to hear the difference ;-).
> Audiophiles have become more insufferable as systems improved.
Well, that just proves audiophiles from the 1980's were right: They told us, that there can be better systems. It's just, that those developments, back then, were expensive and new, which resulted in high product prices, while today they are common main stream.
