In terms of:
Sound Card -> USB (Mini System has USB support called "USB Link")
Sound Card -> AUX/Gameport (Gameport is for video game consoles but in reality its the same thing)
which of the 2 is better? like if i continued using the AUX from the mini system to the sound card of my PC, will i notice a difference in SQ if i used the "USB / USB Link" part instead? To me it doesnt sound any different....jw if the USB has any advantages somehow lol.
edit: Sound card is a Sound Blaster Live! 24-Bit.
