Woo hoo just got my K712's! I hate how long AKG's take to burn in...
Did you listen to them yet???
Things "opened up" with time, but I thought they sounded quite good when I first got them (Used, but used little).
Just got a new cable from Zombie_ZX, I've never compared cables before but it sounds great, physically it's nicer in a few ways than stock (though sleeved in black, personally I like a little color but black isn't bad). I'm not sure if it's the cable or the tube I'm using ATM, but I've never heard Wilco's music more crisply, staggered by the detail & transparency (this after spending most of July's head time trying out the DT880). Instant musical-pleasure shivers!
