I ended up recabling my P7s. I had a hard time looking for a connector to fit, so I modified one (this took about 2 minutes). Anyway, for anyone that's thinking about making one, I am experiencing SIGNIFICANT transparency and soundstage improvement (twice the Soundstage). Also, the bass seems to be almost unaffected, but the mids and highs are much better in every way. I'll definitely order some solid silver and make another cable asap, but just wanted to tell you guys that the stock cable appears to be inhibiting a lot of the potential. Beware, however, that it makes it appear a lot less "bassy" since the it balances every other range out (but It's extremely natural now).
P.S. Excuse the color scheme.... heatshrink is going to be over everything in the next day or two ;).
Edit: So I was so appalled by the results of the recable that I decided to "step it up" a little. Trashed the pictured cable and decided to make a paired cable (using the same strands from before...just doubled). So I managed to comfortably fit 18g total per channel. I can easily say that these produce the best audio I've ever heard as of now, and trump the soundstage and fidelity of my old k701s with silver AND my old triple fies with a silver cable. Protip: If you're planning on recabling yours, go with a twist instead of a litz braid... I'm seeing physical benefits in the earcup. Also, these are benefiting SIGNIFICANTLY from the extra copper. I the highs cooled off too, and I verified it with a session of old Metal ;).
