Lets all keep in mind that mbd2884 has some serious 'radical' opinions about some stuff, some stuff I truly disagree with. However he is in his full right to express his opinion in any way he likes, the same as everybody else. I know mbd doesn't need anyone to stand up for him, because he is more than capable of doing this for himself. I'm just trying to put my point across, that even if you don't agree with him/her, they still are allowed to say it. If mbd2884 thinks Sennheiser is more capable of making the better headphones, well he is right, they made the Orpheus. However the priorities in current markets lie not in the same as ours. Think (Sony R10, Sennheiser Orpheus, Grado HP1000, AKG K1000), the most neutral cans aren't in production anymore. If the HD650 or a Grado presents the sound more natural, is actually a personal thing, and has alot to do with the perception of sound.
Cheers!
