Guess what? I broke my headphones! When I was trying to repair the cables for the thousandth time, a piece of solder got into the membrane and burnt a hole in it. Then, the solder ball got stuck on the edge of the membrane, and it was a pain to get out. So, now I'm going to be headphone-less for about a week.
I repurchased the pro700mk2 used off of amazon, and went ahead and purchased a refurbished pair of the AD-900 headphones. Both of the headphones together only cost $301, so it isn't too bad. I could have bought the DT990/600, M-100/LPx, DT770 Pro 80, or even the Pro900s, but I strongly believe that the drivers in the Pro700mkII have so much potential, more than the aforementioned headphones. I'm going to repeat my mod on the pro700mkII (remove the white tape stuff blocking the holes in the drivers), and transplant the drivers in the AD-900. I'll make a thread once I get everything in if you guys want to follow my progress.
I was going to buy a Schiit Lyr too...guess I gotta wait now.
