Chrome Sparks - Marijuana -Really great electronic song to test the lower end Nick Hakim - I Don't Know -Impeccably recorded blues, to test the lower end. On the LCD series, the song feels lush and deep. On the HD800s it feels galactically open. The Singers Unlimited - Killing Me Softly -Each singer is individually mic'ed; just a lovely song. A great test of soundstage Submotion Orchestra - Amira -Instrumental uptempo electronic song. Not that well-recorded a track but it gets really busy at the end with so many layers that on most headphones it sounds muddy. This song is how I confirmed the HD-800s was a special kind of headphone, because everything was more separated than I was used to hearing. Bayonne - Gift -A good test of instrument separation. Sort of the same as the submotion song above. Bayonne is famous for one-man performances using looping systems. This one gradually adds more and more layers. Bassment Jaxx & Metropele Orkest - Samba Magic -Metropele Orkest need no introduction. This song tests stereo imaging, I imagine from the perspective of the center front row. The applause sounds behind and to side. It also happens to groove so hard.
