Hey there! It's been awhile, but I resolved my original ground loop problem with a little isolator plug, but now my headphones are certainly growing long in the tooth, and I'd certainly like to upgrade sooner than later. I'm looking around the $1k range. Coming from the 4XX, I really enjoyed their staging, and clarity, though I'd like a bit more emphasis across the mids/lows. I'm primarily undecided between Ether CX, and LCD-2. A few other choices I've considered, though not as strongly are LCD-2C, Aeon Noire, and HE6SE. I'm admittedly biased towards another planar, and as far as music, I have alittle bit of everything. Classical, Rock, Electronic, Hip-Hop to name off the genres I listen the most of.
