Well, I 'll just keep the e17 then. Money is a bit tight now. I just went to the local cans store today to buy a 990 pro for my friend and saw the mk2. Too bad i didnt test it with the he 400 since the store is crowded. but I got a chance to test the d7000.
D7000 seems emphasized vocal a little bit and the bass is more impact compared with he400. The sound is very good but its 995usd price tag is just too much for me now. comfort wise I think its better than 990 pro, perfect weight and clamping. In just wish denon put velour on it. The leather is hot and sweaty.
Impression for he400 after 2 weeks. Mine is rev2, since the rev3 is cancelled by hifiman. Sound wise the he 400 is neutral, nothing is emphazised. Atleast to my ear, i might be wrong. But I like it. I find it less tiring to hear than ie8 and m50.
1 thing i missed from ie8 is the soundstage. I think the He400 is smaller, but not much from ie8. I might be wrong but again, its my ear.
envy, I noticed you got 650 on your sig, care to give a review for gaming with it?
Thanks for this useful thread.
