@Humpleupagus @charlie_root @Zerglingman @Xenophon @BiggusDiccus I had 4 pairs of 701s and returned all of them, none of the cups were matched. I used AD900s non-X for a long time but I ended up trading them with a friend's A900Xs because I realized that mixing on headphones is mostly a waste of time in my case and KSC75s will do just fine. I have my sights set on <400€ planars but that's already well into meme territory as far as I'm concerned.
