I’m using them on my x570 motherboard and wonder if I would get a noticeable increase in sound quality by getting an amp/dac.
Maybe, but probably not. If you have the option to grab a Schiit Fulla, Fiio K5 Pro, or KA1, and return it without many questions, then you could find out.
I have the same question. I get enough volume with no hissing sound with HD 560S plugged directly into headphone jack on pc. I’m not sure if an external dac just increases volume or/and betters sound quality.
It would just make it louder, DACs are are pretty mature technology now unless you want things like additional outputs, etc you don’t need another dac
Maybe, although my friend has an X570 and it sounds okay, I have witnessed OEM audio outputs that are not okay. You don’t need to spend serious bucks, just get the Apple dongle, or a Scarlett Solo.
