I will be upgrading my PC music interface shortly from Xitel to a CA Dac Magic Plus or other comparable upsampling DAC. I currently use a USB port of my XP based PC. The CA has a USB input as well as optical and digital coax inputs. Since I only have USB on my computer I was thinking the USB most convenient but wonder if these other digital forms offer a better signal?
I have a basic sound card. No optical or digital out. Does it make sense to get a better sound card and utilize either of these outputs rather than USB?
I also notice that Acoustic revive offers a HiFi USB interface but that seems pricey.
