Schiit Lyr/Bifrost combo.
I actually ended up liking the SE-535 more. Well, I think so. I've been using them a lot more. It's just really hard for me to go back to the 4R, because it sounds to me like the 4R has a veil over it. Like a thick layer. I know that's not the case. Having had the 4R first, they are very neutral and wonderful IEMs. But my ears can't adjust going back and forth from the 535 and 4R. And maybe it's just preference, but I'm finding a lot to love about the 535s.
