Nice review man always happy to hear about the HD 700, I like the An Justice for all album as well! 

I love this headphone too

Nice review. I was laughing because you test equipment with the same music I do. It works because we have listened to the songs so much that we just know them. If the rendition is correct or an improvement like in your case, it's perceivable. Cheers, now I want to try em!

I use the black album all the time to test gear.
