Hello,\n\nI am having a marantz sr7012 av receiver with Monitor audio speakers in 9.1 setup. I frequently play music from my PC via optical cable. \nMy PC motherboard is ASUS P8Z77-M bought 5 years back. \n\nNow recently an opportunity to connect a friend's PC based on new MSI Z390 Edge motherboard, I observed a lot of improvement in the background sound quality of my music tracks.\nso i am considering to buy a new music card\/DAC for my music system.\n\nI need advise from this forum to proceed which way. a PC sound card or DAC \nwhich is best for the Marantz sr 7012. My budget is around 300~500$.
