@myap, since you're in Singapore, why don't you head over to Jaben @Adelphi and try on the TH900s for size? Listen to them through your iPhone or iPod and see how it sounds to you. They might also have the D7000s but I KNOW they have the TH900s since I auditioned them @Jaben in Feb while I was visiting there.
You'll get a LOT MORE answers than going back and forth on the forums here, in multiple threads, where folks with varying degrees of opinions are going to even further confuse your picture of the situation.
Since I have the TH900s and I tried them out of an iPhone 5 and I got no satisfaction out of them, compared to driving them through a headphone amp, that is just my opinion. You and others may be perfectly fine with it. It really depends on what your approach and mentality and perception of listening to them will be, nothing any of us can give you a definitive answer on.
And yes, I agree with Girls Generation on the statement that "they're two very different headphones" when you're comparing with the LCD-2s. But like preproman stated, ANYTHING Is up for comparison. I was just comparing Stax Lambdas to the TH900s yesterday in limited use cases, even though I wasn't intending to since they both sound different.
Also, I wouldn't be riding the MTR with the TH900s during rush hours in SG. You will likely come home one day with a busted pair of TH900s. ;) So think twice before you consider the cans for iPhone/iPod use!
