Hey! I just got my new mic, and it sounds fantastic, but the headphones I have are dying, and I really don't want to use the direct monitor port on my umc202hd. I've been looking at dt990's and hd 599's or 598's, or hd58x. I come from having sennheiser hd 439s and I want to try something different, like open-back which is why I have been looking at those headphones. I don't want to spend too much money on the whole group, so like maybe $170 max for headphones, and maybe $150 to $200 max. I saw many people run the schiit stack, or now more frequently the jds labs atom with a topping d10/d30, but I don't want to spend too much, as I have about $500 or so, and i'd like to keep some of that money if possible. What would you recommend?
