I think Peter of Double Helix modded his HD800 with solid core silver internal wiring before?
Anyways, it's a nice touch; perhaps not necessarily essential, but a nice touch nonetheless. Tralucent is at least showing attention to detail that they easily could ignore. For example, their cables at least have their own branding on their Y-splits and 3.5mm plugs. They're using right angle pin connectors. Normally, HK/China-based companies just use those silly "UE" connectors, and that's just ugly.
