Recently built my cousin a PC for use as a golf simulator. The setup would also function perfectly well as a cinema room. I'm not so into audio except iems so have no clue on what kind of setup would work well? I'm assuming some sort of external amp could be plugged into the pc easily? 3.5mm jack?? And then the amp feed the speakers. Could anyone recommend anything . Say £200 budget? Not sure if that's adequate?
