I'm looking to replace the cables on my HD580's since I've gone through two pairs of the stock cables over the past 2.5 years and both have eventually led to spotty sound on the left side. I use them just on my computer (A2 ZS, cheapo Rolls amp) for gaming and music so I'm not looking to spend a ton of money (<$75 would be ideal) but want something that's good quality and will last longer than the stock cables have. Any recommendations?
