I ended up grabbing some AKG K240 mkII's as they were on for a good price at my local shop (cheaper then internet, woot!). They seem pretty highly regarded on DSF as well as other audiophile/studio forums I checked.
I was honestly expecting to feel like I wasted my money when A/B'ing them to my 700's, but boy was I wrong. Everything is so crystal clear even at low volumes. I've never owned headphones of this quality before so I had no idea what to expect. And they are light as hcek too, I forget they are on my head.
