Hello i got a headphones with very large soundstage, but im puzzled how to connect them to my ps3. i have the AV cables sound set up with a E6 fio amp, but will that give me position location in my games and in movies? also i heard there is a USB connector for audio and mic. Im not sure which one to use to provide with the best audio surround. Im not planing on buying a MIxamp or another sound processing device.
