Alright - the HD800s are such a beast. In a great way.
A while ago I've built myself a badass copper cable with high-end wires, soldering and good connectors and I think I am right now clocking 150-200 hours on it. I swear it's transformed from when I first listened to it. It adds strong body, bass presence, musicality and a hint of warmth to my HD800s. The treble is still really well extended but actually my HD800s are now less sibilant prone than the LCD-3s. The latter is with silver cables.
Recently I've added an interface (AP2+IFI IUSB) to my upstream and that's also added another couple of notches of flow, detail, smoothness, musicality and extension.
The slam and the energy are still surprising me, it's the N-th time the last couple of days and I am still getting surprised by it.
I keep getting amazed how much the HD800s scale when fed the proper sauce. If anyone tells me again the HD800s sound thin, lack bass, too sibilant, I could laugh, but I will say ... please have patience and build a system around them and you will be GREATLY rewarded.
