Thank you. I did search the forum before posting but I didn't find this. Lots of info here to go through. :)

Thanks for the cable info guys. Next question, got a magnius/modius stack to go with my he-560. I've read the planar loves power. Is this enough to drive it to its fullest? Or did I screw that up too?

Yes, saw that. But I thought I read the V1's use 2.5, hence my dilemma, they're inconsistent. I'm a dingbat, I'm pretty sure I ordered the wrong (expensive) cable, 2.5mm. Newbie mistake.

Hello all, new here. I just ordered the HE-560 v4 from Adorama. I think I screwed up with the XLR cable I ordered though but can't find any definitive info on whether the headphones use 2.5mm or 3.5mm connectors. I ordered dual 2.5mm to male XLR to connect to a Magnius/Modius Schiit Stack...
