@Africsnail How low is the volume when running the DT880 250 Ohms on the mobo? I am in the same situation as you.
I am thinking to buy the exact same cans and plug them into my Z390 Asrock Phantom gaming.
I came across with video and the guys is driving an HD650 300 Ohms from his high end mobo. Makes me wonder if it’s really worth it to get an Amp+DAC
If you manage to get your amp, please let me know if it was worth it.
