Thanks for the posts guys.
Jason- We should get together and/or swap phones for a while once I get these broken in a bit. I'd love to hear them through the Grace.
Noah- Thanks for the links. I ended up getting a Creek OBH-11 I auditioned it against the Grado RA-1 and found it more detailed and a bit tighter. Also $150 cheaper
I've been very impressed with the combo so far. I gave Let It Be Naked (LP) a thorough listen the other day and I can't wait to see how these cans sound after the 100 or so hours everybody seems to suggest they need to fully break in. If the 701's were wireless I might consider selling my speakers.
