newly updated "studio" pics of my rig...
Pico sounds real nice esp the mids, very smooth and transparent sound.
I use Silver for signal and copper for grounding in my UE cables.
The adapter is for my ease to plug diff earphone / headphone out for testing.
I actually had made right angle Neutricks plug for my combos but dun really like it, prefer to be this way.
Yes its silver for signal and copper for grounding.
