CK- Another advantage of the 702 is that you can rewire them easily with an aftermarket upgraded wire, if you believe in that sort of thing. I bought the Double Helix Cables Nucleotide for my 702's and like it a lot.
Whatever you do, make sure you run the 702's in for many hours before you pass judgement. Takes a while for the sizzle to die, bass to bloom, and midrange detail to come forward, but it will and you'll notice the changes as they come.
Enjoy!
