---ANGRY RANT WARNING---
Ok, I am apparently too clumsy/stupid/frustrated to make a **** interconnect. I fumbled around trying to fit these *** wires in the even more ***-up plug. I used neutrik 231 mini connectors like these:
and a microphone cable with 2 wires and copper shielding which i intended to use as ground pole on the connectors. then I went after the manual on page 1, and after about 30 minutes the damn wires were finally in these microscopic holes. Another 30 minutes and several burned fingers later the little bastards were in place. aleeve over them, screwng up the housing of the plug and a bit of heat-shrink, repeat on the other end in about the same time... the great moment: I plugged it in and... heavy noises, one channel went missing and reappeared when i turned the wire, bent the wire, and whatnot. --> DAMN. Ok, must have done it wrong - everything out again and anew...
I did the whole process for about 3 times before firing the destroyed cable in the bin and putting the plugs away for later use. I even tried different cable, three single wires from an old adapter (cinch --> 3,5mm like above) and again the same process. With the same results.
ATM I use a 75cm cable to connect my DAP to my amp and that sucks - so what now? The worst thing: when I twisted the small interconnect the right way, it sounded way better then the blasted 75cm crappy cable I am using right now!
