I don't know if it was my head tricking me, or the dac or anything else, but i started getting headache with my modded sa1, like ultra sound vibrations or something like that that gives a bit of ear pain, could be just my ears, I don't know, but was getting ear pain. Again, maybe not related, but I removed the jumpers and will try again like this. Anyone else experienced this thing?
It could also be that I had two different dacs connected and on, only one playing music, but, maybe that was it? I will test and check that...
