Hello, i just bought a pc350 se and it sounded a little bit off. after some research i found that i would mist likely need an amp but that depends on what my current audio is. right now im using the onboard audio on my asus z170-e. i was hoping if someone more knowledgeable about audio than i am can tell me if that's good enough to power the headset or if id need an amp and if i do need one, which one would you recommend? im hoping for something that isnt extremely expensive so if its possible id lile to keep it under $120. Thank you
