Im guessing i will have to run a cord from my soundcard to the amp, then hookup my headphones, but i have no idea how these amps even are, but from my reading they help drive the headphones and improve sound, so im guessing i will need one.
Just one other question, how do the Ultrasone PRO 750, PRO 900 stack up against the Ultrasone HFI 2400 ???? just curious, thanks again.
