Connecting my Asus Xonar DX to my receiver

Hello guys,
I am newby in this field and I do not throw my money away buying smth wrong.
I purchase an Asus Xonar DX and now I would like to buy the DENON AVR-X520bt receiver with 5.1 speakers.
My question is: the sound card has capability to decode Dolby Digital live and Dolby Pro-Logic II, but my desired receiver has only Dolby TrueHD (wich I know is superior to DD live and DPL II). Wich sound type the receiver will be able to decode?
ps: I will connect my sound card to AV optical in with S/PDIF, as it is specified in the Xonar DX manual.

Thanks in advance for your support.
