hi im going to purchase the beyerdynamic dt990 pro, and i will use the audio technica at2020 as my mic, my problem is powering the dt990 pro, im pretty sure my msi g45 wont power it and im at my limit with the budget so i was thinking would an asus xonar sound card power it? any help appreciated
If it is a recent gaming board like the Z87-G45 Gaming (the first result when I googled what you wrote) then it has a headphone amp incorporated, will drive the 250ohm DT990 cans just fine and an add in sound card will not be necessary.
Please respond with the exact model of your motherboard.
