Hello, I used a fiber optic cable _ Dell xps 420 to Pioneer vxi74 . The sound is outstanding . good luck
I ran RCA cables from my onboard audio (an Asus M4A785-M motherboard) to a Technics SA-EX140 receiver. The sound is very faint, though, and contains a lot of noise (i.e. buzzing). What would be the most likely solution for better audio in this case, upgrade to a better pc audio card, or upgrade to a better home audio receiver / amplifier?
