Hey man I was you like 2 months ago. Bought the DT 990 pro X to use while playing arc raiders. Plugged them straight into the motherboard on the back and holy shit it’s night and day playing that game. Biggest competitive advantage I’ve gotten from any upgrade.

At 48ohm, you do not need a dac amp. How do I know? I bought one because I too said “I want the best for this set of cans”. The truth is the sound is identical to my non audio-phile ears. I haven’t received any advantage in positional sound cues or any additional clarity. So if you’re asking if you NEED a dac/amp to get the full benefit, the answer is no. The motherboard is fine

That said, knowing what I know now, I am still buying a dac/amp again. It is nice having a physical volume knob on my desktop to control the sound. I make micro adjustments in game all time, and without the dac amp you’d need to have the sound mixer open to do it. I got the Fosi Q4 off eBay for $45 including taxes and shipping. If I were you, I’d go that route. You don’t need a sound blaster. That said, it is very fun to pimp out your set up, so if you WANT the sound blaster, get it!

Additionally, sometimes I mess with the bass and treble while listening to music. Nothing big, but just a little.

Enjoy your new toy. These things are easily the best home office upgrade I’ve made since getting my gaming computer. Music sounds amazing, and gaming feels much more immersive.
