I think what is very important to Ded is directional A3D imaging for computer games....which Grado's aren't good at. Someone NEEDS to do a test to answer the question, "Which is best for A3D computer games, the Denon AHD-750, or the Sony MDR-V6?"
Heck, maybe we could try and throw the Denon AHD-950, the Sennheiser HD-495, the Sennheiser HD25SP, and the Beyerdynamic DT250-80 into the test, too, to see which is best.
*sigh*
