LOL!!
FYI, the original D7000 was developed by Fostex for Denon. Not sure about the whole American leadership bit (maybe a reference to the Denon-Marantz merger), but the spiritual successor to the D7000 is not the D-7200, but the Fostex TH-900.
I mean, at this point I'm still glad we have a manga about headphones, even if so damn many inaccuracies are there. The Fostex chapters were atrocious on that matter, T20RPs MK3 are still not really good headphones out of the box.
