Hey guys, first of all I'd like to say what's up :D
I've dabbled a little with headphones but this is my first real breaking in. I had a pair of ATH-A700's that my friend broke a while ago and I missed them so much so when I saw a pair of DT990's on sale for $129 on Amazon, I jumped. The problem is these are 250 Ohms and my old A700's where around 64. My little Asus Xonar DS can no longer power such headphones. I understand a DAC helps separate noise but from what I've been told, the DAC on my DS is better than the one in the Magni. I also heard that tube amps sound better with the DT990's so I was wondering if I should just buy a decent $200 tube amp instead of buying the entry level Schiit stack and then upgrade to a quality DAC later.
TL;DR: Should I buy a good amp and then upgrade my DAC later if I already have a decent sound card (Xonar DS)
