I did not compare HF-2 and MS2i directly since I sold both of my MS2i's sometime ago, so please take a grain of salt.
I always thought MS2i's sound a little bit dry, and HF-2 is easier on ear, sound fuller especially in lower frequency and it has more detail. To my ears, HF-2 is clearly a step up.
Mine is coming early next week and I believe it will be the "F1" version. Exchange for another pair isn't a good idea since we have to pay tax or duty.
Hope JG or Todd won't disappoint us.
Which receivers have better headphone out for listening music? I know Marantz and H/K have Dobly headphone, Yamaha has Silent Cinema, while Onkyo and Denon have nothing....
Do these gimmick have anything to do with stereo, music actually?
I'm sure he ignored many others, but this is what he posted

really? FF3.5 is faster than Chrome on my Vista laptop and about as fast as Safari 4, I haven't tried Opera 10 yet, but Opera 9.6 is really slow from my experience.
