**Don't be intimidated by that bass increase on the 1540s, you don't even hear the difference. What i mean by that is the D600s still sound more bass heavy than the 1540 even though the above graph says otherwise.**
Damn you, now I'm having second thoughts on getting the 1540s.
The reason I find the Mad Dogs extremely appealing is because I can upgrade them. The Alpha dog is easily an end-game headphone for a lot of people, including me, so being able to just "upgrade" your headphone, rather than selling your old ones and buying something new and completely different...is a bit...meh.
But the Shure look more comfortable, and have a far better build. Would you say they're far ahead than D600 in terms of SQ though? Barely improved, or what?
