Guys, i have a question. If i use the optical digital cable, can my speaker produce better sound compared to the normal jack cable?
If you use an optical digital cable (or coax) you will be using the DAC (digital to analogue converter) in your speakers (as I'm currently doing now with my S730's from my motherboard). If you use the normal jack cable, you will be using the DAC from either your sound card/motherboard/mp3 player or whatever and sending the analogue signal to the speakers.The DAC converts digital signals (1's and 0's) into an analogue signal (waves). Mind you, you can easily spend thousands of $USD on quality DAC's.
Try both, let your ears decide.
