Hello every one!!!! Currently i am switching back and forth between my sennheiser hd 599s and my ath audio technica ad 500x headsets. As of now ive just been plugging them right into my pc and using the on board sound board. I want to kick it up a notch and get a dac/amp. I dont want to spend a million dollars but im also not cheap. Should i get a dac and a amp seperstly and use both, or should i get one of those combo sets thats both in one. I game everyday and stream so i am really serious about my gaming. I mainly play fps br game. Mainly warzone 2.0 right now. So any suggestions would be great, thank you?
