Hello I got myself a new Maximus 8 Ranger motherboard which has Supreme FX sound on it which is told to be best motherboard audio. In my current build I am usin Xonar DX souncard wit unofficial driver, because official actualy sound bad at least for me. I must state that I only use TOSLINK output and no headphones. I heve a 5.1 system with high quality floorstanding speakers and a Harman Kardon AVR5500 reciver. It is unit from 2001 and I wont replaci since it sounds better than most never ones, it has 16 kilos by the way. I am usinx xonar for Dolby digital, but Supreme FX uses DTS.neo. No problem for me because receiver can use both encodings. My question is if supreme FX isbetter than 8 year old card for optical listening or not and if someone has any experience. I am asking in advance as I am still waiting for my RAM to have all the parts for Skylake build.
