I just auditioned the Sine yesterday. Great headphone, albeit small. Sounded more detailed and more balanced than my HE-400, by a noticable amount. But still fun sounding.

I tend to like on-ears, for some odd reason. I like portability, especially with the sines cipher cable. I think I am going to buy it after the Purpleheart.

I cant see how the HE-500 or 560 could really obliterate this headphone... maybe in sounstage and imaging, but the Sine is already so clear and well defined..

I don't think the 560 obliterate the 400i. There is a reason people recommend the 400i over the 560, and it's likely because the price difference is not always worth the difference in sound
