Indeed, as if they'll ever prove people can't hear a difference.
On a similar theme, this is from Nuno Bettencourt, guitarist with Extreme:
''When we heard 'Eruption', we were just, like, 'Wait a second. Wait a second.' Go back. Listen to it again. Listen to it again. It was just a different level of technicality, but also creativity, and it was just so innovative. And you know what? For me, that stuff, 'Eruption', was one thing. I'm talking more about the rhythm playing. Edward was doing something where all the guys before him, while they were playing their rhythm tracks, if a change to a section happened, it was always the drummer who did a fill, who did something to make a change. Edward was now — we were hearing a guitar player and going, 'Wait a second. We can also have fun with rhythm playing?' He's doing fills, almost like drum fills, going into sections, having fun and putting a smile on your face and really being creative and playing little vignettes of solos for — I don't know — a bar or two in between sections. That was something really fresh and new. It made you go, 'I can be creative with rhythm playing.' That was wild."
Now he is clearly hearing things that very few people can hear. I would guess that 99% of die hard Van Halen fans aren't hearing this. They can follow the lead guitar easy enough, but the rhythm overdubs? I doubt it. I am believe the same will be true with cables. Some will hear a difference, some won't. I'm guessing Nuno will be able to!
