I never took the challenge but I thought it was an interesting topic to start.

Disagree? That’s okay. Take the challenge!Think you can hear the difference? First, test yourself! Try an honest blind listening exercise. We’ve found that in just about every case where someone claims to hear a difference, they have never actually tried to discern it in a proper blind test.
One way to test your self is to download an ABX testing program like [[url=http://="http://www.youtube…"]foobar 2000[/]="http://www.youtube…"]foobar 2000[/] for PC or https://itunes.appl…"]ABX Tester[/]="https://itunes.appl…"]ABX Tester[/] for Mac. If you’re the first on record to reliably get it right when comparing 320kbps mp3 or 16/44.1 to any higher resolution format, we want to be the first to hear about it.
