My old boss had a pair of those Grados, I remember they sounded pretty nice for hifi headphones.
I use Beyer DT-770Ms and absolutely love them. Amazing isolation and super clean. In fact they're so clean it is a bit of a problem because you can generate dangerously high SPLs without them distorting so you need to be careful not to damage your hearing without noticing it.
Been meaning to post a pic since I first saw this thread but haven't got round to it til now, but me and my cans are mixing sound for a life drawing class so plenty of time to post stuff.
I've also got a pair of Aiaiai TMA-1s which I bought for travelling but they just don't compare to the 770s in terms of sound so I hardly use them. I put up with the bulk of the 770s because they're so excellent.
