I know a lot people don't want this, but I hope Fang just tunes the 400i to be like the 560. I like neutral flat sound without coloration. If he has to color it up a bit, than I can settle for the shelved upper-mids of the HE-500 + mid-bass hump. But it cannot have that flabby bass. It must be tight.
But yeah I'm hoping the 400i = 560 with just a tad bit less refinement without wood, but 90% of the 560.
My 2 cents, YMMV, etc, etc.
